OK, I'm thinking I know the answer to this, but right now what I am doing is this:
Let's say I have a shirt that has S, M, L, XL, 2XL as the sizes and Black, Purple, Gray as the colors.
That generates 15 variants. However, there are just 3 different colors. Do I actually need to upload a picture to every variant?
If the answer is yes, I am going to suggest that you create a way (within the product for instance) that a different picture can be added to the main variant (color in this case) and have it apply to all the variants generated. It would make management of the products much easier.
Let me know if I am doing it correctly/the only way. Thanks!
