Catty - I did a Google on geotagging and understand it CLEARLY now.
Put this picture in your mind ok? You know when Army/Navy wants to find a location, they use satellite to find locations by longitude and latitude? Like for example Longitiude: 1234578.5 with Latitude: 5889911 then the satellite zooms to that specific spot right?
Well...now think reverse....if you enable geotagging...when you take a picture..the picture will get info from your phone's gps of WHERE you took that picture. So, if you take picture in San Juan, Puerto Rico and you show the picture to your friends. Your friends say BS you NOT THERE....if you smart or if your friends are smart..they can find the latitude and longitude of where that picture was taken. (that info is supposed to be attached to the picture...how you get it..I dunno yet) and they can GULP...yeah catty right..catty was in San Juan when he take that picture. Here my source:
