I live in a semi-rural area that has a county museum with a section on family histories. People are encouraged to organize their photos, especially if they go back a ways, with proper labeling, names and dates, in albums, with introductory letters or stories. If there are family histories or diaries, those can be included. If they're properly organized, they can be donated to the museum at the time of death. They won't take batches of unlabeled photos. They're looking for something that will show the history of individuals and families in a linear order.

The local Mormon Church helps people organize because they have a great interest in genealogy. You can also get organizing info free on-line.

This is not the sort of thing the Museum of Modern Art would be interested in, but museums that specialize in local history, the history departments of community colleges and universities, some libraries, and other similar organizations might be interested in a well organized family history and photos.

I also have a friend who has no family. She puts her photos up on-line and several have been used in books. She has an inexpensive digital camera and no training, but she has a good eye for the historic aspects of life.

In the meantime, I hope you enjoy your photos yourself in whatever way you can. I have no photos of my parents, only one of my brother and none of my sister, due to a family member who hoarded all the photos for themselves and wouldn't budge an inch. So it goes. Some people, huh?
