A circular door more than 5 meters tall stands open between two tunnels, a man standing at the base looks very small.

Most of the images on this site are from U.S. Government free image archives.  Some have been Photoshopped more or less extensively.  There are some amazing free images available from the U.S. Government, which can’t copyright them, so they are free to everyone to use.  Your tax dollars at work, and a good thing, too.

Here’s a few of the best sources:

NASA Image Gallery

US Geological Survey EROS project

National Human Genome Research Institute

National Science Foundation Multimedia Gallery

NIST Image Gallery
