Product gallery becomes scrolling page

Hi,

I need to basically replicate the functionality of this page:

…where the product gallery functions basically just as a vertical list of images with links to scroll to them, but then at smaller sizes becomes a regular slider. I need to do this in a woocommerce website.

Before I delve into it, I was wondering if anyone knows of a plugin with this functionality? Or has any advice for the approach?

The page I need help with: [log in to see the link]
