Display thumbs of your photos at their locations on a map

[cvp]

If you are using MapView, like in demo of @JonB, you can display thumbs of your photos at their locations, with their original proportions or cropped and centered squares or even cropped and centered circles.
Assuming you pass the path of your photo as subtitle of anotations. In this case, the photo have to reside at an accessible path for your script (local or iCloud).
