Because the photograph is taken and saved in the camera in digital form, it can be sent back to earth as a radio signal. Once converted back to digitals it can be viewed on a computer as a photograph again. If film was to be used, the exposed film would need to be physically returned to Earth for developing before the photograph could be viewed. Photographs stored in digital form (1's and 0's) will not suffer from aging as does film. http://spaceplace.nasa.gov/en/educators/earth_from_space.pdf http://spaceplace.nasa.gov/en/educators/teachers_page2.shtml http://www.google.com/search?ie=UTF-8&oe=UTF-8&sourceid=navclient&gfns=1&q=digital+space+photographs
