Is there a way to search for products missing images in the admin?
Hello!
In Magento admin you can only look through products, not aware of bulk default means. For older Magento versions there are a few queries offered over the web, for M2 found the one on Git, but not sure if this will suit your version specifically. There is also tool Manager for M2 with this functionality. Saw free version to do this for one-time without having to pay.
Yes. I had the same problem and built this this module to this easy. Hope it helps.
