Kirinke, I can't help you on their part but if your have something in mind I don't mind trimming it up and tossing it on my web space for you. (Avatars don't take up that much room and I'm not charged by bandwidth.)
You need a relatively small photo, or a big photo with a relatively small <insert cute object> but besides that its really simple. My email is in my profile if you’re interested.
Edit: Holding Avatars goes for anyone... Just make the email subject very apparent or it will probably not get open up.
