Select portal row image

[Rainy Pass]

I want to set up an interface that works like a browser shopping cart, where one (main) image is shown with a row of smaller images representing different colors of the main image. I want the main image to change as the user selects a smaller image.

Currently I have a layout based on a Style table with the image displayed thru a relationship based on style num. A portal shows all the available color images for the style.

How can I change the displayed image via the user clicking on a smaller color image?
