Is there a way to do one of the following:
1. Have a page that includes images that link to either a collection or a product
2. Change the Collection Image clickthrough URL to go to a product page instead of the Collection page.
For the 2nd one post the code of your collection.liquid file code so I can tell you where to edit to replace the link with the products link.
For the 1st one, Simply create a page template and add the following code
<a href="YOUR COLLECTION OR PRODUCT URL" ><img src="YOUR IMAGE URL"></a>
Hope that makes sense, you can contact me if you need my help with these.
