Looking to update your desktop wallpaper? Having trouble finding anything good. Ask Wallpapr to find something for you. It’s a nice, simple Ajax app that will spit out a bunch of photo wallpapers from Flickr’s Wallpapers pool on command. Just enter a tag (e.g. clouds, skyline, food, whatever you’re into) and click on 20, 40, or 100 to get that many thumbnails, or leave the tag field blank and get a nice variety. Every photo in the pool is at least 1024×768, and clicking on a thumbnail will take you straight to the photo download page. Excellent!
