First of all, thanks for the heads up.
Can anyone tell if it's really just the amount of graphics that adds up, or if it's the problem of a busy server that's slow when answering requests?
(Possible way to tell: the first page you view will always be slower because the graphics are loaded for the first time. But the next page should be much faster because most images are already stored in your own cache.)
We already introduced a hard limit that restricted avatars to 6kb and sigs to 10kb. Maybe that's not enough? Or how about a check box in the user profile where registered members can chose NOT to view other people's sigs and/or avatars?
Either way, maybe it's time to get a server upgrade.
