I've had, in the past, the title screen to Phantasy Star IV, a series of drawings that I liked (some of which were done for me), a promotional art picture for Sword of Mana, a wallpaper from the game Mabinogi, and a few others. Right now, it's a default, as I just had to reinstall my computer from scratch. When I figure out what my newest wallpaper will be, I'll post it.
