Photo Siege allows downloading tagged photos and photo albums from Facebook. You can download your own and your friends' photos. Once the photos are downloaded, you could view them without an internet connection or set them as wallpaper with your Pictures application. You could also transfer them to your PC for archival purposes. Simply login with your Facebook account and start downloading photos with a single tap.
