I think it's the md5 of "Violin_case.jpg". http://pajhome.org.uk/crypt/md5/ shows "Violin_case.jpg" -> "c08f6840732b9d9c6c7d7b6e71f04616" and "Tetris.jpeg" -> "f80e1fb8ec92fbd63688b29ad53a9af" so http://uncyclopedia.org/wiki/Image:Tetris.jpeg is at http://uncyclopedia.org/images/c/cf/Tetris.jpeg which is correct! However, this behaviour may change in the future (I think it's unlikely) so you should probably look at the MediaWiki code. Also, thumbnails aren't made just because you visit the URL. http://uncyclopedia.org/images/thumb/c/cf/Tetris.jpeg/180px-Tetris.jpeg http://uncyclopedia.org/images/thumb/c/cf/Tetris.jpeg/190px-Tetris.jpeg So maybe you need to call some MediaWiki code for it to be generated.

I need some information about commons, i.e.: i've got something like that: [[Image:Violin case.jpg|thumb|right|200px|Skrzypce w futerale|]] and i wanna link it to: http://upload.wikimedia.org/wikipedia/commons/thumb/c/c0/Violin_case.jpg/20…. What I need is the unknown part of url string: "/c/c0/", how could I establish it? I've been looking for any data quering wiki's database, but i don't see useful information, unfortunately. > > Thank you. > > Greets, > Piter.
