Need help editing my wiki stats

i recently made a new ava, and i'd like to reflect that in wiki. can anyone tell me how i can delete the avatar "Andy Zammy Zam" in the wiki database? it is also somehow linked to my account. also, i'm not quite sure how to add new avatars into it.

Clear your Cookies, then make a new acc in wiki

You could perhaps edit your old avatar.

If you go to you "account page", by clicking on your username on the top right corner (while logged in), you have a drop-down menu that allows you to associate/disassociate and avatar with your account.
