Hello, I've built a shopify store for worldwide printing solutions, My knowledge at shopify is not that good,
I want in my site the customer will be able to upload his photo and choose size and material.
so my request is:
-Photo upload - I'll decide the minimum resolution & pixels so I'll get photos on high quality
-Photo match - I need that the photo will match the size.
ex. I've uploaded my photo and then It shows me avaible sizes for this specific photo(so if the pic is 3000:4000 pixels, the only sizes i can choose is 3:4 ratio)
