Emailing Geo-Tagged Photos
Select one or more photos that have been geo-tagged (whether automatically by your camera, or manually as described earlier), and then click the Mail icon in the bottom toolbar of the iPhoto window.
In the dialog that opens next (see Figure 10), select the "Location information" option and then click the Compose Message button. When you send the email message, the GPS location information is added to the photo. The recipient of the message can add the photo to iPhoto to view the location information, or can use Preview to view the location, as described in the next section.
