is it possible for an external image not present in the product to be loaded as a preview image for a specific collection? The image should only be loaded in the selected collection and should not be loaded generally in every collection. Also important, it should/may not appear in the product images.
Unfortunately this doesn’t work somehow. The collection also contains several products that require a respective image, not all of them the same. I forgot to mention that at the beginning. I think this is a much bigger effort, right?
