How do you add avatar to your signature?

 

[Psyfira]

Click on "My controls" (top right), then "Edit signature" in the menu on the left. You can put pictures in in the same way you do on messages (if you're unsure how click the "IMG" button to put a picture in.)
Be sure to check the forum rules first for picture size limits

Lol his sig was too big, now his avatar is like 10 kb over the limit.
