Purchase An Image To Associate To A Product

[JustImpression]

Hello this text is translated from Italian to English.

 

I PrestaShop version 1.6.3

 

I have this problem ...

 

We sell many different products, customized with images sent by customers.

 

Now I would like to create a gallery of images, in this way, the customer buys the image and associate it with a product that I sell.

 

I have to make sure that the product, once purchased, it also decreases the amount.

and the image must be available

 

how can I do?

 

 

Thank you all
