here's collaborative aerial map of vancouver, which i made so that i could geolocate some images i took when i visited in may. by clicking on the areas under the tacks you can 'zoom' in. then you can add notes to those images with the text format [photo]flickrimageID[/photo] and your images will appear whenever someone clicks "expose photography locations"
