If you mean the little pics under our names, LEE has quite a collection of BB2 housemates photos and if you let her know who your favourite was she can sort one out for you. You can either send her a U2U message or let her know here.
If you'd like someone else as your avatar and have the picture stored on your computer, you can e-mail it to LEE so that she can make it the right size and put it up for you.
Hope this helps.
