I’ve implemented something like this before, and would recommend making it fetch the “next” and “previous” images instead of the one actually being requested, to make sure the image is available when it slides onto stage, but an interesting method (using HTML Comments, rather than simply hiding via CSS, which doesn’t work the same everywhere).
