England
The gravestone photographic resource project has managed to photograph and index cemeteries in a number of English counties.
The greatest number of cemeteries have been index in East Anglia where the project is based.
However, cemeteries in other parts of the country have been photographed by volunteers.
If you live in England perhaps you could help the project by taking photographs of you local cemetery and sending them to the resource: see how to be a volunteer for more details.
