I Do not remember if this was covered as part of another thread, but just wanted to post it for those that are trying to fly under the radar
"Geo-tagging works in very simple way. When you take a picture, the Geo-tagging software along with the GPS program in your phone places a marker on your picture with the exact location, time and date the picture was taken, and sometimes it already has a map attached to it. It gives an exact longitude/latitude location for anyone who has the know-how to access it. And once a criminal has you and your property in thier sights all they have to do is follow your postings to find out when you aren't home and break in. This works with some digital cameras too. When you post a picture on Facebook, even when your settings are set to private, your pictures will come up on Google Image search in most cases, the Geo-tags are embedded in those pictures too."""

And it does work on a photo sent to a pc
