All you nature lovers who love to decorate their desktops with beautiful wallpapers of nature, here is something that might be of interest to you.
NatGeo Wallpaper Downloader is a freeware and portable software, which allows you to download wallpapers from National Geographic automatically. Club it with a wallpaper changer/rotator and you will get to view the best of nature whenever you visit your desktop.
Oddly, the software does not provide you with an option to select screen resolution for 2009 National Geographic wallpapers.
