At least one of my friends asked about getting a display userpic like the one I’m using now. Stupidly, I neglected to include the URL of the gentleman who does it. The page from which you can buy a userpic for just GBP1 is here. You send him GBP1 via PayPal, and he’ll reply to you with a request for a photo. You attach the photo to an email (or give the URL of a photo already online), and he does it in a day and emails it back to you.
What could be better?
