title: Delete woocommerce products without featured images
body: <p>I have more than 1500 products without featured images. I have to delete it. 
  I found a query to get list of this products: </p>
  
  <pre><code> select ID FROM wp_posts WHERE ID NOT IN (select post_id from wp_postmeta WHERE meta_key="_thumbnail_id") AND post_type="product"
  </code></pre>
  
  <p>and I found this plugin <a href="https://pl.wordpress.org/plugins/woocommerce-products-without-featured-images/" rel="nofollow">https://pl.wordpress.org/plugins/woocommerce-products-without-featured-images/</a> but I can't delete product from it...</p>
  
  <p>both things do the same thing</p>
  
  <p>Can you hint how can I remove these products?</p>
