Pick&Zip is a simple web application that lets you easily download Facebook photographs with a few clicks.
You can download photos tagged with your name, your own albums, photos tagged with friends’ names, or your friends’ albums. After selecting the photographs you’d like, you can download them as a ZIP or PDF file.
I just tried it out, and the service works pretty well, allowing you to pull photos at the highest resolution Facebook stores (720px) quickly to your computer without having to click and download individual photos.
Something that’s slightly annoying is that you can’t seem to download all possible photos with one click, but must “select all” on each individual page. The app is pretty useful, nonetheless.
