Primary Image Set up

-- url of the page with the problem -- : ark.developwithrgb.com/natural-dog-products
-- HikaShop version -- : 2.4.0
-- Joomla version -- : 3.4.1
-- Error-message(debug-mod must be tuned on) -- : I am not getting an error. I just need to know how to set up the images so that the image set up as primary shows up as the primary image on both the product and category views.

So basically I want the primary image on this link:
ark.developwithrgb.com/natural-dog-products

to show up on the product page as primary on this page as well
ark.developwithrgb.com/natural-dog-produ...-healthy-wags-plenty

Whatever I set to 0 becomes the primary image on the product page.

Whatever I set to 1 becomes the primary image on the category page. So the primary image is not the same for the product and category. Where do I change this.
