Profile pic on upload side
 

I just joined, used a catch-all Gmail account, somehow your sure grabbed a photo of myself that I must have uploaded to that Google account and plastered it here as my Avatar pic.

I don't like that, and I can't change/remove it

Please remove it, or delete my account.

Sure you can, you can adjust it and upload new avatar and use it, and then the old one wont be shown at all.

You can access & edit your account profile via the User CP button found on the banner above.
