You can only upload certain file types from your computer.
Try saving the image online, like in Photobucket.??Then upload the url from there in the corresponding field on your Upload Avatar page.??So long as it's an image file (JPG, JPEG, GIF, PNG, maybe [maybe] BMP, but not TIFF or anything Flash) and not over 120x120 pixels it should work.
I had a time trying to upload an avatar on another account and it wouldn't accept it because it was too large.??I did everything I could to the file but it never got below 60kb (Max upload is 10kb).??And even then it looked crappy because I had to put it in JPEG at a really low quality.??I then found out that if I uploaded it from the net it didn't matter how large or what file type it was.??So, I saved it to Photobucket, uploaded it to my Av page and haven't had a problem since.
That is, until Anti-Sec decides to hack Photobucket.??xp
