Animated Avatars and the Default Avatar Size

My response to above message:

So my question is: What is the default avatar size for SRK?

Note: I’ve experimented with 150x150, 200x150, 200x200, and 160x160 but have been unsuccessful at retaining animation.

If an admin would respond, would be super! Thanks for your time.

I agree and support you, I’m just a Mod however.
Let me see if I can get this under a Admin’s attention.

Appreciate the support, Diek Stiekem!
