Hello I am working on my first shopify store and encountered an issue. I was wondering if it is possible to add an image to an order, so that I can see and use it when proccesing the order. I only found a way to do this with the user uploading an image of their own. In my case however my website generates an image I would like to use. So I want to add the image generated by my website to my order. How could I do that?
