If you don't want to create your own cache of the image files, you
would need to do a proxy of sorts. Your plugin would basically add a
rewrite rule then echo the appropriate Cache::get call for the
requested uri. So you might have /latex/some-hash-string.png, and
plugin retrieve 'some-hash-string' from cache. This means for every
request you load Habari twice, which is not great...
The other way, as I mentioned, is to create your own cache dir and
save the generated images there, linking to them directly, thus not
loading Habari twice.
note: You SHOULD NEVER NEVER NEVER link directly to habari's FileCache
data; in fact on my server I set cache dirs to a non-public facing
folder (not in docroot)... in my case define('FILE_CACHE_LOCATION',
'/var/www/mattread/cache/habari/'); in config.php.
