You are trying to replace your avatar? There was an issue awhile ago where someone was trying to replace their avatar and kept uploading a file with the same name as the avatar they currently had, and it wasn't overwriting.
thats me, any way i can change it, really irratating im sick of my the big lebowski avatar, any help would appreciated, ive contacted mods but they said theres an issue with it, ? thanks, been driving me nuts
As long as you upload an avatar with a different file extension that you haven't used previously it will work. That means you've got 3 avatars at most (JPG, PNG and GIF) and then you're stuck with those three. It has nothing to do with the approval process; it's definitely a bug.
