Okay, I'll provide the log as an link in the wiki. But there should be a kind of mechanism how they can be removed. This could lead to an DOS (create via a bot so much nonsense code that the disk is full.)
> The url handling could stand to be improved. Currently it uses $config{url}, so it depends on that being set. Some ikiwiki builds don't have an url set. The thing to do is to use urlto(), to generate a nice relative url from the page to the image.
>> Mh... i choose one single dir explizitly since if you use on several pages the same formula this would really improve the time to generate the formulas and it would waste extra space if you store every formula 3-4 times. But if you really like I'll change this behaviour.

Yes of course, I'll improve the url handling. My comment was only about the several folder ;-)
> Another (minor) problem with the url handling is that you put all the images in a "teximages" directory in the toplevel of the wiki. I think it would be better to put each image in the subdirectory for the page that created it. See how the `img` and `sparkline` plugins handle this.
> It looks like if the tempdir already exists, tempdir() will croak(), thus crashing ikiwiki. It would be good to catch a failure there and fail more gracefully.

Fixed. I'll removed these two lines completly.
