I'm trying to duplicate a site for a client who wants it redone in a CMS. They have a thumbnail strip across the bottom of portfolio pages with clickable images...but clicking the thumbnails doesn't simply change the main photo--it also changes out the text content.

I was going to take a different tack, and have it redirect to a new URL entirely. But to do that, I need to have an add-on that allows the end user to specify a URL whenever they add to the thumbnails--otherwise, they'd never be able to add to their portfolio themselves, which defeats the purpose of having a CMS.

An example from the present site ishttp://www.ads-architects.com/portfolio.php?category=category&t...
