I'm working on scanning in some high quality pictures for the site so expect to see a a lot of files added within the next few days. I currently have a bunch of pencil boards and art books for Lain, Trigun, Rurouni Kenshin, Oh My Goddess, Sailor Moon, and Escaflowne and am waiting for ones that I ordered for Neon Genesis Evangelion and Gundam Wing.
All files are in 1024x768 and are high quality jpegs. You can click on them to bring them up in a new window, and then right click and set them as wallpaper directly from your browser, or save them instead.
Gutzs from the boards was kind enough to give me some of his wallpapers so be sure to check them out - too cool not to download @_@. New additions include Berserk Wallpaper from Rall!
