All of the wallpapers are sized 1440x900, but I can resize them on request (I think they look alright, if a bit squished in 800x600 or 1024x768, but I don't know about other resolutions). The banner-things were sort of done on a whim and you're free to use them for... whatever, I guess, as long as you credit me. Feel free to resize or tweak them for your own nefarious purposes. :D Onward!
