Add new product template

I have a WordPress Woocommerce site, and I messed up and accidentally deleted the section on the right for adding a product image when adding a new product to Woo. I thought “no problem, just close and reopen the add product page”, but no, the add product section is missing from the template, and is also missing from any page that I open that contains an existing product. I suspect that some file on the server has been updated to not include this information, but I don’t know which file to edit or what information to add to that file to restore the product image section. Does anyone know who this works?
