Wix Stores Adding an "Upload File" Option to Your Product Page

Currently, it is not possible to add an Upload File option to your Product
Page which would allow customers to provide more details (e.g., images) about
the product they want to purchase.

As a workaround, you can add a customer message box to your Product Page so
customers can provide more information.

Update:

It's now possible to add an upload file button to the Product Page using the
Uploadly third-party app. Note that the app comes with a 3-day trial period.

We are always working to update and improve our products, and your feedback is
hugely appreciated.
