Thank you for your answer. Would it technically be possible to add this functionality? Or would this mean a complete rewrite of the sunshine photocart?
The problem in this case is that I would have to direct customers to two different private galleries. Experience tells that only about 30% manage to look at both galleries.
The other way would be to have incorrect product categories for certain images. This will lead to incorrect orders and confusion.
Both of those scenarios will lead to less ordered images 🙁
