- There are browser add-ons and extension apps that can read and report data on forum images that are taken with smartphones with geotagging (GPS) turned on. This so called EXIF data is stored with the image and can include make, model, aperture, date, etc. and, if you have GPS tagging turned on
, the location where the photo was taken. The most sensitive of this data is location as free software exists that can read and open that data in Google Maps. You may not want that.
Photo storage sites such as Photobucket, which many members use, can turn off this data in the User Settings, Privacy section. Storing and allowing this information to be read is the default, but I have set my Photobucket account to the following. You may want to do the same... or simply turn off the GPS when you take photos (and save some battery life as well).
