Hi,
You should use configure your HikaShop menu option in order to not display the "add to cart" button (Backend: Display > Content menu).
After that, if you want to add some HTML code in order to put your "read more" link and image. You would have to edit the listing view.
You have to check your type of listing (regarding to your screenshot it should be : listing_img_title) and edit the corresponding view: "Your front-end template | products | listing_img_title".
The link is already display in the product name so you could use the same code.
