TBF, these "hidden" autostereograms are the most challenging to "see" - it's probably better to start off with two "actual" pictures printed or displayed side by side (because there you have some cues to how far you are from the images overlapping), and then try to apply the same technique to autostereograms? I can manage to do it most of the time, but it always takes some effort. I think it also helps if the image is bigger, but YMMV...
