These are great Nats avatars, it maybe fun swopping them around.
On the subject of graphics, one question, unless I'm using the wrong skin or something and can't see it, have you never considered a Nats/WNFF banner/graphic at the top of the page where that big white space is?
Are you talking about the top of this page? If you are, you should see a graphic and not a white space...

If you are talking about the Avatars page, the answer is no.
