jdf0 on "Lightbox not working :("

Hi everyone. I'm currently working on a project for a client. He requests the images open up in a different window but on the same page (lightbox).

I've had it work on other sites that I've worked on in the past. For some reason, the images open up in a new window and NOT in lightbox.

Here's the "testing" page. Do note that the page isn't finished and I put only one image to work right now.

Here's the site that I am following for the lightbox:

Before this, I've tried every popular lightbox plugin. They all have the same problem. They open up in a new page. Please, all help would be greatly appreciated!
