Trying to add an avatar to my profile from http://img.photobucket.com/albums/v6...AtWork/sjs.gif

Image size is 75 x 75 and 2 KB, which is under both size restrictions of 80 x 80 and 14.6 KB. However when I try to add it I get: Upload failed due to failure writing temporary file....anyone that can tell me what I'm doing wrong and how to fix the problem would be appreciated.
