A similar thing happened to me when I lost a phone in Vietnam. I ended up having to remotely nuke the phone in order to stop the photos when a few images came through of a family visiting a grave. Too creepy.
I wonder how common/repeatable this is, and what the minimum requirements are for a device to get picked up and used this way. It might be an interesting art project for someone to plant a few tens of cheap smartphones around, assuming we could reasonably expect at least several of them to broadcast interesting slices of people's lives.
