  3. How can it link photos to GPS coordinates without wires? • GPS-Photo Link downloads the photos from the camera and the GPS tracklog or waypoints from the GPS receiver. Next it matches the timestamp from the photo to the closest timestamp in the GPS data. What if the camera and GPS are not set to the same time? GPS-Photo Link allows you to correct for differences when you run the program.
