JavaScript Help: Example of Timed Interval Image Swapping

This is an example using JavaScript to create a timed interval picture book. You can use this technique to create JavaScript slide shows, or anything else which requires images to swap in a timed sequence. This runs picture swaps a limited number of times, then stops and (if supported by your browser) changes the opacity of the image to indicate the picture show is inactive. (Refresh to restart the show... or tweak the functions to permit a restart feature.)
