Those are very nice, indeed!
However, this site only allows Avatars that are 64x64 (I may raise it to 72x72 in the future), and that load up quickly for dial-up users (for now, until most people enter the 21st Century
) Certainly, 2MB avatars won't cut it here.
So keep that in mind - 64x64 or 72x72 (square!) and less than 50k (less than 5k if I'm hosting it)... because this site is about content, not flashy graphics (obviously
)
But again, very impressive.
