But I dont want to resize the avatar, that would lead to a bunch of jacked up avatars. I just want to disallow oversized avatars. I am using the sub silver template and have changed a few table and background colors but those are the only changes I have made.
It is nearly impossible to restrict the size of remote avatars. Thee are ways around it. That said, that MOD is a good way to go. Also set a rule on your site about avatars. When people break that rule, warn them and then temp ban.
