Are you SURE?
Prove it.
Post a screen capture of your account from a laptop or a desktop, and prove that I don't understand what you are talking about. I'll bet you that your avi shows up just fine next to your account name, message envelope, bell alert, and search magnify glass icons.
I do understand. You are telling us, that your avi picture is not displaying properly on your phone, and you are paranoid that it is a conspiracy of the folks that run the forum. I get it just fine.
Does your avi display normally in other areas besides just that blue bar?

Is it being whited out else where?
