How to insert non-product image in collections page

[krose2]

I would like help to add a non-product image to the collections page which links to another page (e.g. sale collection, sign up offer, shipping offer etc.). I am using Dawn theme. I have included an example to demonstrate what I am hoping to achieve.

Do you need banner in between the products ?

[krose2]

Yes please. I'd like the option to add two banners in between the products on a collections page. For example, the 4th image and the 9th image of all collections could be a banner. The banner would need to be the same size as the collection product image.
