Glad you like my pictures. I honestly don't remember where I got my MGM Sorcerer's hat clipart... I've had that saved for a really long time and then added my name to it and have been using it ever since. I can't remember where I first ran across it, sorry.
My avatar, however, (the little picture of Cinderella's Castle) is more recent, and I remember where I got that one from. It's from here: http://www.***********.com/id240.htm On the left there's a bunch of links with pages filled with avatars like mine. Enjoy!
