Forum:What happened to my pictures?

A few pictures on my wiki have just disappeared. When you go to their URL, it says "No file by this name exists, but you can upload it.", yet the file page has licensing info and categories, so the picture was definitely uploaded. It's just disappeared! Does anyone know why that might be? Examples:, ,. The uploads have gone from the upload log, but I can tell you I definitely uploaded them. I have sent this to special:contact, but wondered if anyone else had noticed instances of pictures sneakily just vanishing?-- Category:Acer4666 13:39, November 30, 2011 (UTC)
