Chris,
Pleased to be of service. It was good to be in Brum again even though the weather was a little inclement (ohh matron)
I see you intend to write the address on your photo. Good idea.
Do you use meta data on your digital photos? Now that most of us have swopped over to digital photos there can be thousands of pictures on our computers without any descriptions. I give each photo collection a name. It can be as simple as Susan's wedding/ September/ 2004 or include a list of the people and places shown. Then all you have to do is enter your search details to show every picture which has a common word. i.e. Susan. (not that Susan is common you understand)
Depending on which utility you have to store your photos it's worth checking about adding meta data tabs and can be a much better way of spending a rainy day than 'taking pictures in the rain'
