Welcome to LakerNation.
Do you have a link to the image you want as your avatar? If there are issues with sizing, I'll fire up Photoshop and edit it for you, but it could also be an error, so I'll gladly look into it for you.
WOW! That is mighty kind of you! Strangely enough, I don't get any type of error message or anything of the sort. I upload, save changes, refresh and it just doesn't show up. I really appreciate your offer to help.
