Now create small versions (preferably around 300 px wide) of these five images and place them in the thumb folder. With this we are good to proceed to the code.
We will create an array of images and their names, which we will display in a dropdown. Selecting an image will display its thumbnail. Clicking on the thumbnail will display its larger version in the jQuery UI dialog box.
