JavaScript display of multiple images within a png file

purplesoup used Ask the Experts™
I believe it is possible to have a png file with multiple images on it, and have them rendered separately using JavaScript., However I've not been able to find out how to do this. Can anyone assist me?

Just to be clear, I can follow this

But what I'm looking for it something more  flexible, where the png file has various images positioned within it, and the JavaScript can access the images separately, to overlay one image on top of another, not simply adjust the offset of each image.

What you're asking about is called "CSS Sprites," or perhaps some extension of that which uses some JS.

In CSS sprites, you basically use background images and then set the background-position, background-repeat, and background-size properties as needed.
