I love sharing photos on Google Maps the most, because I like taking lots of photos while I am visiting interesting places. Even if its just a visit to the seaside or a country house; I like to share my experience on Google Maps with the photos I take.
Photos also show pending visitors what to expect when they get there. What that areas they intend to see when they reach the destination.
The excellent things about photos is that they are so universal as anyone of any language, can view and feel like they are there with you as you took the photo.
When I look at the number of visitors to the photos I have taken on Google Maps. I just hope they have the same pleasure viewing the photos, that I had when I took the photos.
