Here is how the page appears in Mozilla Firefox.
When each thumbnail image is clicked, the larger version appears in the main frame. Also, when the main image is clicked, it moves onto the larger version of the next thumbnail.
Here are the images in the XHTML code. The onclick event calls the appropriate Javascript function. For example, the function required for the first image is gal1.
This is the Javascript that makes the gallery work. When the first thumbnail image is clicked it calls the gal1 function. This function shows the element with the id g1, which is an img (the larger version of the thumb) and hides all of the other large img tags.
