I've just been playing around with trying to set up a product display similar to that provided by WooCommerce. I have managed to get something fairly close and quite pleased with the result. It would only be a matter of adding the necessary Snipcart or Shopify Lite code to turn it into an ecommerce site.
This is the product list page:

When you click on 'Read More' it takes you to the product page with a main image and more images as thumbnails below.

Clicking on any thumbnail opens all images in a lightbox (currently Featherlight).

Can share the code if anyone is interested.
