Thousands of people upload pictures to TwitPic or other Twitter supported photo sites not knowing that the pictures they are taking contain location data. If you have a GPS enabled device that takes photos, it is very likely that your photos are embedded with the location where they are taken. Here’s how location data can be extracted from an image uploaded to TwitPic or similar photo repository sites.
2. In Firefox, go to the page that contains the Twitpic picture or other site with a picture and right-click on it.
3. Select View Image EXIF Data.
4. Scroll down to the EXIF GPS IFD section. Note the longitude and latitude.
5. Search the location on Google Maps.
The location where the photo was taken is found.
If you don’t want your location data included in your photos, there is usually a setting that can be turned off on the device.
