Try this at home:
- Open a geocoded photo in Preview v4. If you don't have a geocoded photo, here's one of the Warrumbungle National Park from Siding Springs [warning: 4.7MB file] that I prepared earlier. Save it to disk before opening in.
- Choose Inspector from the Tools menu.
- Click the 'i' tab in the Inspector window at the top in the centre.
- Click the GPS tab in the second line of tabs in the Inspector window.

You should see the location data for the photo and the photo's location on the map. Click the Locate button to see the location of the photo in Google Maps.
