Oh, there are lots of stills photos of the missing scenes, including some stills we have no idea of what scene that would be (like one showing Dave and Frank in b&w, showing their futuristic wrist watches). But the cut scenes are pretty much lost. I bet Kubrick even take measures to make sure they kept lost, I mean, he BURNED all the stage and 99% of the props so they wouldn't be used by anyone else or sold by fans (only some stuff like those red chairs and a helmet are still around).
