Image Navigation (with example)

Hi, 

I'm having real difficulty replicating the "Home" page on the following website:

https://www.mpkelley.com/

I am using the supply template, which I can see is also what the above site is based on. I am trying to create a home page with a single image, that can be clicked on to open the next image, as shown in the above. I'd like to be able to use the same arrow-based navigation, or at least something similar.

You will see in the bottom left of the example home page, there is a "prev/next" & "show thumbnails" section, which it would be great to have too, but not essential.

I'm new to this, so maybe I'm missing something obvious in the template options?!

Any help would be greatly appreciated. 

Thanks, 

It looks like they're using the Wells template not the Supply template.

You're absolutely right, thank you.

The photographer whose example I was using has another website, that was made using the Supply template. Suffice to say I wasn't paying enough attention. Doh.

Many thanks for your help!
