I am searching in the source, but I cannot find it anywhere.
I want to change the cached image filename pattern to something like, something_posttitle_postid_somerandomnr.jpg
I found that I can change the cache dir, but I am sure that I will need to make that change every time I update the plugin.
define('YAPB_CACHE_DIR_NAME', 'yapb_cache');
It would be nice if this can be changed from the settings page.
