Recently I described my effort to add GPS data recorded during a road trip and a canoe trip to Google Maps.  I had written some JavaScript to import my data into a map, with a few options for customization, but felt that there was more that could be done with the data from the canoe trip.  I had a number of photographs from the trip and a desire to map them, along with the GPS data, at the positions at which they were taken.  Although the photographs did not contain any meta-data providing the GPS coordinates for the location at which they were taken, they did contain meta-data indicating the time at which they were taken.  Since I had a GPX file full of time associated geographic positions, I decided to fuse the two together.
