Profile pictures

[Kira]

If I'm not mistaken, VIP members are able to use bigger avatars.

Note: The maximum size of your custom image is 200 by 200 pixels or 250.0 KB (whichever is smaller).

This is what I have, what's your limit?

This is a useless suggestion I say no, besides, it would make that when someone loads a thread or goes to a profile in here, it would make the loading slower, depending on the size of the gif picture of the profile/thread

there is a forums option in your settings that allows you to disable signatures and even custom profile pages.
