On the other hand, if I don't try to hold the image and let my mind wander, I find that with no effort at all I can build infinitely complicated and unique images and sequences of almost anything, objects, landscapes, faces, patterns; like if you could printscreen my mind I guarantee you would get a museum quality masterpiece each time.* But I can't 'hold' these images either, they just flit by very fast; an interesting observation, the more tired I am the faster this gets.

Is your question "Why is it hard?", or "How does it work?" I am sure that the 4 year-old version of the question didn't take into account that you are a ****ing horrible observer with nearly no memory.
The first is easy. It is hard because it would be hard to code it. Your memory (beyond a couple of seconds) is no better than a tweet with some things hard coded (specific faces are pretty well hard-coded for the vast majority of us)
As for the second, there is no value in you having the ability to remember fine-but-non-salient details of actual events, so no reason for you to have the ability. You are well-built for playing around with the salient stuff and moving little bits of this sort of salient thing around to see how it affects other salient stuff without actually trying it out.
Just enjoy the light show.
