I have just found the most amazing desktop wallpaper site: Interfacelift.com. I must have spent over 30 minutes looking at wallpaper and saving it to my desktop. The download time was almost instantaneous and there are a variety of resolutions offered. The pictures are just gorgeous and you can specify whatever category you want. I really have to tear myself away from it because I do have things to do, but I'm looking forward to going back to look some more, as I like to change my wallpaper frequently. There's also instructions on how to submit your own pictures.
