Xbox live gamer picture not visible to friends?

I use one of the default gamer pictures on my xbox and when i put it on it just shows up as a blank to everyone on my friends list, if i try any other gamerpic for example my avatar one it shows up. Any help would be appreciated, thanks!Xbox live gamer picture not visible to friends?Try putting the picture you want as your "private picture" ( which only friend can see) and your "public picture" ( everyone else sees this).
