am supposed to grab one of the moving images and pull it over to match it with to one of the other moving images
You ask above if are you supposed to do this and such....well, did you, to see what would happen?
That's what makes it a puzzle, you have to try different things to see what works, not just stare at it.
It's just like doing a jigsaw puzzle laid out on the table you know....you find the corner pieces and the edges, and fill in the rest.
You're just overcomplicating it.
