Avatar problem

[DK]

I have an avatar, But it won't let me use it, because the filesize as a jpg is too big. I changed it to a gif, but then it looked crappy. Any idea of what to do? This really sucks ;_;

Edit: My photoshop thing saves all the 60x60 pixel avatars at 10.80KB. Why? ;_;. I looked at the other Avatars for use, and they all seem to be jpg, but they're like 2 and a half KB.
