digital photography idea

why don't we enable the storage of the next and previous photograph(s) in the digital file for an image. yeah, sure, it would take up a lot of storage space, but it's often really cool to see other photographs that were taken before and after an image. case in point: I don't know about others, but for me there are certain "famous" photographs, indelible images that have gone from being images that capture a moment to being, well, famous. take an image that's iconic like that for you and try to find the photograph taken before and after that photograph -- the result for me was kind of like a behind-the-scenes of the original photograph. that would be the idea behind this, build in a behind the scenes into every photograph.

this may be more relevant to prosumer cameras (like my canon digital rebel) where multiple photos can easily be taken in succession. and then, what if the before and after photographs were crappy images or simply duplicate frames?
