Open/view images in seperate div to thumbnails

Hi all

I’m trying to figure out how to open an image on the page (as opposed to linking to the attachment) from a thumbnail. I want the thumbnails to be linked from the post, and I’d have a seperate div on the left of the screen to view the large images.

Pretty much like this, but not full screen. https://www.wright20.com/auctions/view/M4JZ/M4J1/111/LA/none/OJYI/0#

Running 3.3.2

Thanks in advance
