How to upload WooCommerce gallery images

Hi, we’ve published a popular tutorial about how to use your Gravity Forms CPT plugin to allow users to upload WooCommerce products via the front end of their website, and then display them on the front end using our WooCommerce Product Table plugin.

A customer has asked how they can upload multiple images to the WooCommerce product gallery (i.e. the thumbnails that appear underneath the main product image on the single product page).

Do you have any instructions on how to do this please? Presumably the gallery images are additional custom fields against the ‘products’ post type. If this is possible, please let me know how to set up the form fields for the additional images and map them to the additional product images, and I will then advise the customer and add this information to our tutorial.

Many thanks!
