This isn't how the brain works though. The photographs are only useful in so far as you remember that they have content in them. How would you know what photos to look at and acknowledge as useful if you didn't already know that the content in those particular photographs were useful for you in aiding the remembrance of some particular event. Really we use this kind of documentation to remember the fine details of events. Brains are great at remembering the overarching narrative but it's bad at remembering much else.
