Of course singular - or linear, say, from bad projection device - defects in that are rather final, and this format has a host of inconveniences like fire hazard, inability to get transferred over networks, comparatively huge costs of copying, large physical size demands etc. We can perhaps use a convenient digital format for images and add to it, ahem, anti-corruption measures. Single file is still going to be vulnerable - even though to a less extent - if you, say, add some Reed-Solomon protection; but now you can use distributed networks the size of a planet, or even more. Organization of such a storage could be an interesting problem - at least partially solved already.
