When tagging your photos, you have the option to geolocate the place the photo was taken by inserting latitude and longitude or using Google Maps to find its location.

You can then browse the world map for the places you have been and see the photos you have taken there. Or share your vacation photos along with a map of where you went.

By using the Animate feature you can create a slideshow integrated with either a road or a satellite map. The effect is amazing. Just try it.
