Any photos that are geotagged--include geographical location data in the image's metadata--may appear in the Places view. Where does the location data come from? If your digital camera includes geotagging features, a location is automatically recorded whenever you take a photo. Similarly, if you've given the iPhone's Camera app permission to use your location, the app adds location data whenever you take a photo or record a video. You can also add location data manually in iPhoto or a number of other image-management programs on your computer.
