DTail, your "profile" pic appears on your public profile page, as compared to your "avatar" which you also have to set. Confusing, right?!
Click on the User CP link near the top of the page on the left hand side. That will take you to your personal control panel where you can set up your avatar.
Btw, I like your fishie. I'm very fond of the double tails, both of my current boys are DTs. :)
