The World-Wide Media eXchange (WWMX) is a set of technologies that features an online database of nearly 30,000 photos submitted by mostly amateur photographers and indexed by location. Downloadable software from the WWMX site (see Related Links, at right) can associate digital photographs containing date and time stamps with data collected from global positioning system (GPS) devices, and then link the photos to MapPoint or TerraServer maps on the WWMX site using the GPS coordinates. Colored dots scattered across a map of the world show viewers where to look for images that tell people's stories.
