Forum Avatars have wrong extension
 

Hi, I recently upgraded from IP.Board to vB 4 and when I moved over the avatars, only the ones with a .gif extension would show. When I right clicked on the missing avatars and copied the image location into my url bar, it showed the correct filename with a .gif extension, even though it is a .jpg file. It has the correct extension in the filesystem and the database. The only place where the extension is wrong is in the forum itself.

Thank you
