I hate these things, but better safe than sorry. There’s essentially only one rule: Don’t be a dick! Download the wallpaper(s), set them as your background image end enjoy. Don’t re-distribute any of the content without permission or try to sell it in any shape or form.
If you’d like to share this page with others that’s absolutely cool. Do not embed and make available for download any of the hi-res wallpapers. You are allowed to include lo-res images and link back to the original download page on Walls of Type.
