i had to uninstall the earth rot live wallpaper. the planet kept going blank/white, but the backround still was there. tried again and it would go into some random non-live wallpaper whenever it wanted to. oh well. i've actually never seen avatar, but i downloaded the avatar images from the marketplace and used the one like on the cover of the box the phone came in, because the image is so, well, so vibrant, with the blue face and the green eye.
