Show image pop-up based on selection

On I set it up so the larger image shows based on the thumbnail clicked.

With JavaScript can I make that “ZOOM” link to the large version of the image that is selected? Any idea how I would do this?

It’s not clear what you mean by that.

Yes… sorry, after I posted this I removed it because it was not working and am working on a live site…

Basically I would like to have a link that when the visitor clicks on it, it will zoom the selected image.

Is something like a Lightbox what you want?
