how do i check which products do not have external image attached
i have uploaded 2500 products to wordpress. each product has mutliple variations. i uploaded a csv that contained a list of tite, and cdn urls. now the majority of the products have a cdn url and gallery attached. on the products tab is there a way to check for products that have no image attached so i can recreate a csv with the cdn url to sort this issue out? is this possible if not what is the best solution to sort this out.
