Help with connecting and copy images between WooCommerce and custom site

:bullseye: What is your goal?

Copy a photo from a custom build site to WooCommerce

:thinking: What is the problem & what have you tried?

I have some products in my woo site without photos, but I have the same products and barcodes in my old site.
I managed to find these products in both sites but I can’t figure out how to copy or download the photos and upload them to the woo site.

Explained scenario: search the products in the woo → connect to the old site via http request → search the same products in the old site.
