I'm talking about the size of it, not the display size. You can't have high quality images on icons on these forums, I mean.
I'm not sure I understand: there's no limit on the file size of offsite avatars (at least not that I've tested, but have seen examples that are quite large) and while uploaded avatars are limited to 97K, uploading isn't enabled. The actual forum icons such as smileys etc look a bit dated in some cases but that doesn't seem to be what you're getting at.
