NASA offers a lot of photos taken on the moon via their site NASA Images.

Virtual reality images of the moon is a collection of panoramas made from high-resolution photos the twelve astronauts who walked on the moon took. (The rest of Panoramas.dk is worth checking out as well, by the way. Quicktime is required to view the panoramas, though.)

From Panoramas.dk:

“Experience the moon just as the astronauts did – almost as you were there. View interactive QuickTime VR Panoramas in full-screen from the 6 Apollo Missions who landed on moon.
The links to the panoramas opens in a new fullscreen window which resizes to your screen.
All panoramas include original audio clips. Most of these are from the minutes around the time for the pans. On the Apollo 11 you hear the famous moment when Armstrong stepped down on the moon.”
