I've started the long involved process of geocoding pictures (adding latitudes and longitudes) to images. I will use this information to create maps. The maps will be in the subdomain: maps.protophoto.com.
At first I was using Google Maps, but I didn't like being constrained by their API and Terms of Service; So, I did research and decided to use the maps from Open Street Map. As I understand the PNG maps are released as Public Domain.
While working on this project, this site (ProtoPhoto.com) started acting up. I fear I may be overtaxing my CPU allotment, So, I decided to develop the maps as static pages.
I hope that this effort enhances your viewing pleasure.
