Scan each picture into a separate word document. You might have to scan the picture and then copy it only a word document. You could label each scanned picture and word document with unique identifiers.

On each Word document, people could identify people, write stories about the picture. It is really important that each comment be identified with a valid email address. I can tell you from personal experience that people’s memories are sometimes different and you might need to research some of the differences.

One benefit of scanning pictures is that everyone can have copies of them and you can preserve them in the state they are currently in. Some pictures fade so scanning them is the best way t preserve them.
