I have a number of image templates for in-app purchase, that stored locally on device. I have created non-consumable in-app purchase in iTunes Connect. Now I cannot understand, how do I, kinda, assign a particular image to a product identifier? Because in in-app purchase there is no option to assign it to particular content. I am probably missing something here. From this question that I have to create new product identifier for each image-template I sell. But this made it even more confusing, coz I cannot understand how to link each image to each product identifier. Thank you.
