It would be _very_ hard to provide the user the output of latex since this is really very much. For an simple formula as \frac{1}{2} this could be 2 printed out. +>> Yes, that's true.

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.
