well from what i've seen lots of peoples avatars are not showing up and i think a few have complained about this problem, my answer to this problem is by hosting other people's avatars\icons on my photobucket account which hasn't failed me yet every pic i've hosted always shows up when i post it somewhere with no problem.
so if your interested and your avatar won't show up then i'll host it on my account and give you a direct link to it and all you got to do is click on the picture, get the link and well you know the rest right.
think about it you'll have your avatar\icon working again and you don't have to do anything execpt get the avatar\icon to me and i'll do the rest.
forgive my nature that sees a problem and wants to help if i can help.
p.s. i'll host any avatar.
so if this sounds like a good idea you know what to do.
