Simple Thumbnail Solution

Suppose you have a series of images in thumbnail and you would like the user to easily browse through them. In this script we will create three thumbnail images and a larger copy of the selected image will be displayed on the right of the screen. We will also highlight the currently selected thumbnail.

This script shows how to use CSS to format your page as well as how to use javascript to dynamically change the CSS properties of the page elements. It also has a DHTML technique to change the source of an image tag. Copy & Paste this into a new HTML file, then open in your browser.
