I have a number of large collections of 1960s colour slides which appear to have found their way to eBay after someone died. I have no way of knowing if it was intentional, and no way of tracking down any living relatives because of the lack of identifying information with them.
My advice to anyone with photographs they want to preserve for future generations of their family is to document who is in them, when and where they were taken, and keep the notes with the photos. Otherwise within a generation or two they will be pretty meaningless. Same applies to digital files of course.
