The original poster stated that this book is just a guide to the location of cemeteries in NYC - it is not an index of burials. To put together a listing of cemeteries is altogether different than putting together an index of burials and the two do not necessarily go hand in hand.
If you have a photo, why not ask whoever gave you that photo where it was taken?
My other suggestion is to go here:http://www.rootsweb.ancestry.com/~nymanhat/cemeteries.htm
this might help you as to location and you can also use google maps to help you with finding cemeteries in the specific location that you are looking.
