Whether you're looking for backgrounds for your desktop, Creative Commons licensed photos, or just scanning eyecandy, Flickr is an excellent place to find beautiful digital images.
Need a simple way to download multiple images? Check out Downloadr (screencast after the break!), a free program with loads of options which makes short work of bulk downloading from Flickr.
Downloadr is packed with search options and fully plugged in to Flickr -- so it can locate and download everything you've added to your favorites. Authentication is also supported, meaning you can download private images to which you have access.
Fire up a download task, and Downloadr asks you where to save the images and spawns a progress window. It also supports Windows 7's Superbar progress indicator, so you'll see a bright-green background when the job completes.
A few things worth noting: Downloadr is considered beta, so you're probably going to encounter the occasional bug here and there. I had a few error boxes pop up, but no actual crashes -- searching, authenticating, and downloading all worked just fine.
