This app simply displays your camera roll photos as thumbnails on a map. This is possible because your iPhone automatically stores the location each photo was taken.

Features:

• Displays thumbnails of camera roll photos on a map.
• Thumbnails are displayed at the location the photo was taken at.
• Pan and zoom map.
• Tap a thumbnail to view the image full screen.

Note:

• You must allow the camera app to use your location for your photos to be geotagged.
• Accuracy of the thumbnail location is dependent on the quality of the location information at the time the photo was taken. E.g. high accuracy if a GPS location was obtained on the iPhone 3G, low accuracy if a cell position was obtained on an original iPhone.
• Outdoor photos are the most likely to have accurate GPS locations.
• Requires an iPhone (because requires the camera).
• Requires iPhone OS 3.0.
