NASA has released over 8,000 high res scans of the Apollo moon mission photographs. This collection is all of the mission photos taken. Many of which have never been seen by the public. There are a lot of behind-the-scene photos that give a unique prospective of the Asutranuts time in space. NASA has uploaded them to a FLICKR album. I've download a few hundred to use as screen saver images.
Here's a post Science.com did about the upload.
