The photo archive at Gimp-Savvy.com has more than 27,000 free photos and images saved on our own dedicated server, consisting of over 2.5 Gbytes of data. The goal is to make this archive a resource for collage and photo-montage using digital image editing techniques such as those described in Chapter 7 of Grokking the GIMP (on our site). The community using this site is encouraged to label these images to make a better index.
These public domain images are taken from a few sources, the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Fish and Wildlife Service (FWS)
