I have two products on my site that are named similarly but easily distinguished by their images. Users sometimes buy the wrong one by mistake, so I want to put the product image on the Shopping cart summary view. By default, this view can be used to add fields of products.
My product images, however, are on the Product display content type. Though the Product display has a product reference to Products, there seems to be no way to get the reverse of that relationship (in other words, to get the Product Display from the Product).
There aren't too many products, so I thought about just adding an image field to Product as well and duplicating all the data, but that is definitely a maintenance problem down the line. Is there a way to get the image on the Product Display with just the Product in Views without duplicating data?
