I've been wondering about an improvement to wikiTeX.
AFAIKS, there is no way, given the raw wiki code to locate an image generated from a section of wikitext on the server.
This would seem to be desirable, so third parties who do an XML export of wiki content can display the wikitex sections
At the moment I'm working on an experimental project (that will be properly anounced soon) that uses javascript to parse wikitext and generate the HTML on the client. Of course, I have no way to generate images so being able to locate the already generated ones on the main server is necessary.
On wikisophia.org's examples the math image is: /extensions/wikitex/tmp/2d129aef84955396d6b7a75c141ea41a.gif
I think some kind of namespace for automatically generated images would be helpful, for example:
/images/wikitex/Wikitex/math1.gif (where Wikitex is the name of the article, and math1 indicates the first use of math wikitext on that article)
