## installation queries from brush
|
|
|
|
thanks for this plugin. it might help me in my application, which is to provide album/galleries which can be edited (ie. new images added, taken away, etc.) through web interface.
|
|
|
|
> That's my goal eventually, too. Perhaps you can help to

|
|
|

i have two challenges: firstly, for installation, i'm not sure what all the files are that need to be downloaded (because of my setup i can't easily pull the repo). so far i have Ikiwiki/Plugins/album.pm; ikiwiki-album; and 4 files in templates/ any others?
|

|

|
|

|
|

|
|

|
|

|
|
|
|
secondly: barring the CGI interface for editing the album, which would be great, is there at least a way to use attachment plugin or any other to manually add images and then create viewers for them?
|
|
|
|

|

## design feedback from joeyh on an earlier version

Not entirely relevant any more.

You had wanted my feedback on the design of this. I have not looked at the
|
|
code or tried it yet, but here goes. --[[Joey]]
|
|
|
|
* Needing to create the albumimage "viewer" pages for each photo
|
|
seems like it will become a pain. Everyone will need to come up
|
|
with their own automation for it, and then there's the question
|
|
of how to automate it when uploading attachments. -J
|
|
|
|
> There's already a script (ikiwiki-album) to populate a git
|
|
> checkout with skeleton "viewer" pages; I was planning to make a
|
|
> specialized CGI interface for albums after getting feedback from
|
|
> you (since the requirements for that CGI interface change depending
|
|
> on the implementation). I agree that this is ugly, though. -s
|

|
|
|
|
>>> Now that we have `add_autofile` I can just create viewer pages
|
|
>>> whenever there's an image to view. The current version of the

|
|
|
|
* With each viewer page having next/prev links, I can see how you
|
|
were having the scalability issues with ikiwiki's data structures
|
|
earlier! -J
|
|
|
|
> Yeah, I think they're a basic requirement from a UI point of view
|
|
> though (although they don't necessarily have to be full wikilinks).
|
|
> -s
|
|
|
|
>> I think that with the new dependency types system, the dependencies for

|
|
|
|
>>> I do use img. -s
|
|
|
|
* And doesn't each viewer page really depend on every other page in the
|
|
same albumsection? If a new page is added, the next/prev links
|
|
may need to be updated, for example. If so, there will be much
|
|
unnecessary rebuilding. -J

|

|
|
* One thing I do like about having individual pages per image is

|
that they can each have their own comments, etc. -J
|
|
|
|

|
|
|
|
* Seems possibly backwards that the albumimage controls what album
|
|
an image appears in. Two use cases -- 1: I may want to make a locked
|
|
album, but then anyone who can write to any other page on the wiki can
|
|
add an image to it. 2: I may want an image to appear in more than one
|
|
album. Think tags. So it seems it would be better to have the album
|
|
directive control what pages it includes (a la inline). -J

|
|
* Putting a few of the above thoughts together, my ideal album system
|
|
seems to be one where I can just drop the images into a directory and
|
|
have them appear in the album index, as well as each generate their own wiki
|
|
page. Plus some way I can, later, edit metadata for captions,
|
|
etc. (Real pity we can't just put arbitrary metadata into the images
|
|
themselves.) This is almost pointing toward making the images first-class
|
|
wiki page sources. Hey, it worked for po! :) But the metadata and editing
|
|
problems probably don't really allow that. -J

## alternative "special extension" design (conclusion: "don't")
|
|
|
|
'''I think the "special extension" design is a dead-end, but here's what
|
|
happened when I tried to work out how it would work. --[[smcv]]'''

Suppose that each viewer is a JPEG-or-GIF-or-something, with extension
|
|
".albumimage". We have a gallery "memes" with three images, badger,
|
|
mushroom and snake.
|
|
|
|
> An alternative might be to use ".album.jpg", and ".album.gif"
|
|
> etc as the htmlize extensions. May need some fixes to ikiwiki to support
|

|
|
|
|
>> foo.albumjpg (etc.) for images, and foo._albummeta (with
|
|
>> `keepextension => 1`) for sidecar metadata files, seems viable. -s
|
|
|
|
Files in git repo:
|
|
|
|
* index.mdwn
|
|
* memes.mdwn
|
|
* memes/badger.albumjpg (a renamed JPEG)
|
|
* memes/badger/comment_1._comment
|
|
* memes/badger/comment_2._comment
|
|
* memes/mushroom.albumgif (a renamed GIF)
|
|
* memes/mushroom._albummeta (sidecar file with metadata)
|
|
* memes/snake.albummov (a renamed video)
|
|
|
|
Files in web content:
|
|
|
|
* index.html
|
|
* memes/index.html
|
|
* memes/96x96-badger.jpg (from img)
|
|
* memes/96x96-mushroom.gif (from img)
|
|
* memes/96x96-snake.jpg (from img, hacked up to use totem-video-thumbnailer :-) )
|
|
* memes/badger/index.html (including comments)
|
|
* memes/badger.jpg
|
|
* memes/mushroom/index.html
|
|
* memes/mushroom.gif
|
|
* memes/snake/index.html
|
|
* memes/snake.mov
|
|
|
|
ispage("memes/badger") (etc.) must be true, to make the above rendering
|
|
happen, so albumimage needs to be a "page" extension.
|
|
|
|
To not confuse other plugins, album should probably have a filter() hook
|
|
that turns .albumimage files into HTML? That'd probably be a reasonable
|
|
way to get them rendered anyway.

do=edit&page=memes/badger needs to not put the JPG in a text box: somehow
|
|
divert or override the normal edit CGI by telling it that .albumimage
|
|
files are not editable in the usual way?

|

|
|
Every image needs to depend on, and link to, the next and previous images,
|
|
which is a bit tricky. In previous thinking about this I'd been applying
|
|
the overly strict constraint that the ordered sequence of pages in each
|
|
album must be known at scan time. However, that's not *necessarily* needed:
|
|
the album and each photo could collect an unordered superset of dependencies
|
|
at scan time, and at rebuild time that could be refined to be the exact set,
|
|
in order.
|
|
|
|

|
|
|
|
Perhaps restricting to "the images in an album A must match A/*"
|
|
would be useful; then the unordered superset could just be "A/*". Your
|
|
"albums via tags" idea would be nice too though, particularly for feature
|
|
parity with e.g. Facebook: "photos of Joey" -> "tags/joey and albumimage()"
|
|
maybe?
|
|
|
|
If images are allowed to be considered to be part of more than one album,
|
|
then a pretty and usable UI becomes harder - "next/previous" expands into
|
|
"next photo in holidays/2009/germany / next photo in tagged/smcv / ..."
|
|
and it could get quite hard to navigate. Perhaps next/previous links could
|
|
be displayed only for the closest ancestor (in URL space) that is an
|
|
album, or something?
|
|
|
|
> Ugh, yeah, that is a problem. Perhaps wanting to support that was just
|
|
> too ambitious. --[[Joey]]
|
|
|
|
>> I propose to restrict to having images be subpages of albums, as
|
|
>> described above. -s
|
|
|
|
Requiring renaming is awkward for non-technical Windows/Mac users, with both
|
|
platforms' defaults being to hide extensions; however, this could be
|
|
circumvented by adding some sort of hook in attachment to turn things into
|
|
a .albumimage at upload time, and declaring that using git/svn/... without
|
|
extensions visible is a "don't do that then" situation :-)
|
|
|
|

|
|
|
|
Ideally attachment could also be configured to upload into a specified
|
|
underlay, so that photos don't have to be in your source-code control
|
|
(you might want that, but I don't!).
|
|
|

|
|
|
|
Things that would be nice, and are probably possible:
|
|
|
|
* make the "Edit page" link on viewers divert to album-specific CGI instead
|
|
of just failing or not appearing (probably possible via pagetemplate)
|
|
|
|
* some way to deep-link to memes/badger.jpg with a wikilink, without knowing a
|
|
priori that it's secretly a JPEG (probably harder than it looks - you'd
|
|
have to make a directive for it and it's probably not worth it)

### bug: unable to vary thumbnail size
|
|
|
|
Hi smcv, great plugin. I am an ikiwiki newbie but so far I've had success using your plugin.
|
|
I've integrated the jquery masonry plugin into the albumitem template and it works great.
|
|
But is there a way to create thumnails of different sizes? I've passed thumnailsize option
|
|
and value to album directive and while it does create the new thumbnail sizes it doesn't use them,
|
|
The 96x96 thumbnails still appear on the page no matter what I do. - jaime

Hi, the plugin looks great, but I am probably too dumb to use it ;( here is what I did:
|
|
created page gal.mdwn with just \[\[!album\]\] directive (no arguments) and subdirectory gal/ with images in form img_1234.jpg
|
|
|
|
when I run ikiwiki, I get something completely wrong though:
|
|
|
|
generated gal/index.html page contains following code repeated for every image:
|
|
|
|
<div class="album-viewer">
|
|
<div id="album-img">
|
|
<div class="album-finish">
|
|
<a href="./"><span class="album-arrow">↑</span></a>
|
|
</div>
|
|
</div>
|
|
</div>
|
|
|
|
So no links to any images, etc.
|
|
|
|
The pages for individual images are generated though, but also not correct. Trails section is perfect, but the main part is wrong:
|
|
|
|
<div class="album-prev">
|
|
<a><span class="album-arrow">â†<90></span></a><br />
|
|
<div class="album-thumbnail">
|
|
<span class="selflink">
|
|
<img src="./96x96-img_2913.jpg" width="96" height="72" alt="img 2913" title="img 2913" class="img" /></span>
|
|
</div>
|
|
</div>
|
|
|
|
This really seems like this should be in the album page and not individul page. It is only thumbnail and not full image. Also the full image is not in the generated html tree at all!
|
|
|
|
I am using ikiwiki 3.20130518, and got the album sources from the links of [this page](http://ikiwiki.info/plugins/contrib/album/) (part manual installation)
|
|
|
|
Any hint about what do I do wrong?
|
|
|
|
Thanks Lukas

### bug + patch: not all images shown on album page
|
|
|
|
Hi smcv, we spoke on irc the other day. Passed `show => "0"` on line 126 in album.pm to remove the limit on the thumbnails shown on the album page. Setting it on the album directive didn't work.
|
|
|
|
--kjs
|
|
|
|
> That sounds like a correct solution. I'll fix that in my branch when I work on
|
|
> this again. --[[smcv]]
|

>> Fixed in `album5` branch --s

|
### bug: thumbnailsize doesn't work
|
|
|
|
As mentioned above by Jaime setting the thumbnailsize doesn't catch either. Or rather if I git push after changing the album directive the generated thumbnails (the image files) are the correct size as set in the directive. The html however uses the default thumbnailsize as hardcoded in album.pm and has broken thumbnails as it links to a file with the default size in the filename.
|
|
|
|
> [[KathrynAndersen]] fixed this, see below. --[[smcv]]
|
|
|
|
>> Fixed in `album5` branch --s
|
|
|
|
Issuing `ikiwiki --rebuild` knocks the system into another gear where the thumbnails show up correctly but this is only due to the html being the same as above (linking to hardcoded thumbnailsize) but the generated thumbnail images are now matching the hardcoded size ignoring the thumbnailsize attribute on the album directive.
|
|
|
|
For me this behaviour is way beyond my skills to sort out (I'm no coder). The albumplugin ikiwiki combo is very attractive to me and the plugin i soo close to working!
|
|
|
|
--kjs
|
|
|
|
### suggested fix for thumbnail size bug
|
|
|
|
I've tracked down the "always showing the 96x96 thumbnails" bug!
|
|
|
|
The problem is in the pagetemplate function, which calls "thumbnail" to determine the name of the thumbnail image to use. As you know, the "img" method of generating thumbnails includes the size of the thumbnail as part of its name (to ensure that resizing thumbnails will create a new file of the correct size). The problem is... that in the pagetemplate function, the thumbnailsize is NOT passed in to the call to "thumbnail", so it always returns the default size, 96x96. Hence nothing that anyone can do will change the thumbnails to anything else. Oh, the different-sized thumbnail images ARE created, but they're never linked to.
|
|
|
|
Here's a context-diff of my fix:

### bug: inability to show more than 10 items
|
|
|
|
I've found another bug. The album plugin doesn't allow one to have more than 10 items in an album section. This is because it uses "inline" to display album sections, and the default for inline is to show only 10 items. So it only shows 10 items.
|
|
|
|
What would be good is if the album directive could have a "show" parameter which is passed on to preprocess_inline, so that users could decide how many items to show (including ALL of them, if they give show=0).

### cbaines' commit to change default thumbnail size
|
|
|
|
Regarding commit `Change the default thumbnail size`: as far as I
|
|
understand it, `size => 96x96` is meant to set the image size to
|
|
be as large as possible given these constraints: width ≤ 96px,
|
|
height ≤ 96px, and the original aspect ratio is preserved. So I
|
|
would hope that 96x96 doesn't distort the thumbnails. What distortion
|
|
are you seeing, and which versions of Imagemagick and Perlmagick
|
|
are you using?

## wishlist + patch: make clicking on the large image go to the next
|
|
|
|
I've changed the behavior of the "slideshow" to show the next image when clicking the large image as downloading a full resolution image is a rare use case in a gallery of this type imho. The large clicktarget means you are likely to unnecessarily download large files otherwise. I can't quite follow the template, album.pm flow so I can't figure out how to put a "download full resolution" link on the viewer page which would be my next step. To achieve the next link i added ` link => ($nextpage or $album),` around line 454 in `my $img`

|

## wishlist from kjs
|
|
|
|
My wishlist for the plugin would include:
|
|
|
|
[[!template id=gitbranch branch=kjs/album6-imgmeta author="[[Kalle Söderman|kjs]]"]]
|
|
|
|
- ~~Reading exif info from the imagefile~~
|
|
- I have now implemented this (in some fashion) and the patch is available in my album6-imgmeta branch. --kjs
|
|
|
|
- ~~Keeping the full resolution image files out of version control~~ Solved
|
|
this by simply creating a underlay for the images. Works out of the box for my
|
|
non cgi workflow.
|
|
- Being able to create new albums by tag or by manually picking images from other albums. Could be a simple comma separated list of viewer names, or even full urls, in the album directive.
|
|
- A counter showing **current image/total number of images in album**. This would mean that you know how many images you have left to click through before you have seen all images in an album. This gives you enought info to decide weather to click through or go back/leave.
|
|
|
|
--kjs
|
|
|
|
> I want the first two of those too, perhaps one day I'll get round to
|
|
> implementing them.
|
|
>
|
|
> For the third, you can get the same practical effect using an inline
|
|
> as documented in the main page. --[[smcv]]
|
|
>> The downside to current behaviour is that clicking an inlined thumbnail will take you to the original album context. Previous/Next image will not match the thumbnails in the inline but the thumbnails in the album. This is a bit confusing for users and prevents using the image in multiple contexts without duplicating the image. To achieve what I'm looking for there would have to be several AlbumViewer pages for a single image. --kjs

## cbaines' CSS changes
|
|
|
|
Regarding the CSS changes: I'll try to have a look soon, work out
|
|
what actually changed (since you re-ordered the CSS, so it isn't
|
|
immediately obvious from the diff), and integrate some or all of your
|
|
changes. Since Joey shows no signs of wanting to merge it, and "out of tree"
|
|
installation is currently a pain, I might split out the CSS changes into a
|
|
separate `ikiwiki/album.css` so that the only thing that needs to be merged
|
|
into style.css (or into local.css) is an appropriate
|
|
`@import` rule.
|
|
|
|
It shouldn't be necessary to add the album stuff to each individual
|
|
theme's style.css unless you actually want an actiontabs album and
|
|
a blueview album to be styled differently, because the IkiWiki Makefile
|
|
concatenates them: for instance, `/usr/share/ikiwiki/themes/actiontabs/style.css`
|
|
is the output of `cat doc/style.css themes/actiontabs/style.css`. So adding it
|
|
to `doc/style.css` should be enough? --[[smcv]]

cbaines, would you mind publishing an album with more realistic pixel-sizes
|
|
of images using your modified CSS? It's difficult to get an idea of how it
|
|
will degrade under conditions like "image size > browser window" with
|
|
images as small as the ones you used. You might find
|
|
<http://git.pseudorandom.co.uk/smcv/ikiwiki-demos/ikialbum.git>
|
|
(`git clone git://git.pseudorandom.co.uk/git/smcv/ikiwiki-demos/ikialbum.git`),
|
|
or the same techniques, useful: it contains images with a realistic pixel
|
|
count, but very very lossy JPEG compression, to keep the size in bytes low.

It's much, much easier to review changes if you use separate commits for
|
|
cosmetic changes like "separate index CSS from viewer CSS" and "more
|
|
consistent indentation", and functional changes like turning the prev/next
|
|
links from absolutely-positioned to floating. I'd be happy to apply
|
|
the cosmetic changes if they were in commits that were literally only
|
|
cosmetic changes, with no functional effect.

For the functional bits: I think I'd have used floating boxes instead of the
|
|
absolutely-positioned boxes that are currently used if they provided the effect
|
|
I wanted. I can't remember exactly why I didn't do that now, but
|
|
it might have been because if the browser window shrinks below the image width,
|
|
floats have weird behaviour (they push the actual image out of the way), or because
|
|
I wanted the entire left/right margin of the image to be clickable to have
|
|
a large click-target for scrolling through the album.
|
|
|
|
If there's something specific that you think is wrong with the CSS in my
|
|
branch, could you please explain it, and perhaps we can come up with something
|
|
that matches both our requirements?
