You must be wondering how it works. Well, when you snap a picture while connected to a Wi-Fi or a 3G mobile network, your phone logs the co-ordinates where it was taken. Using that information, you can then add a photo to a photo map. It a unique and fun way to add photos to your Photo Map, document travels and see photos of other Instagrammers who have been to that place or to a nearby location.
By default, adding location or adding to your Photo Map is turned off for all photos you upload to Instagram. This means that no photos will appear on your Photo Map without your explicit permission.
