I wanted to make images float left or right, so I thought it would be nice to be able to pass a class attribute through the img plugin to the final img tag.

An example of the feature in use can be seen here (notice class="floatleft" and class="floatright"):

And here's a patch to implement it. Will this survive markdown munging? It seems quite unlikely... How does one protect a block like this? Oh well, we'll see what happens.

Subject: [PATCH] img plugin: Pass a class attribute through to the final img tag.
|
|
|
|
This is particularly useful for allowing the image to float.
|
|
For example, in my usage I use class=floatleft and then
|
|
in the css do .floatleft { float: left; }.
