title: How to recursively apply a Featured image to sub pages in Wordpress?
body: <p>If a page is not having featured image, display the featured image of its parent page.</p>
  
  <p>If again that parent is not having featured image, get it from the next higher level and so on till featured image is found or last level is reached.</p>
  
  <p>Is there a solution for this in Wordpress?</p>
