ok well i added another condition to the php that adds the featured image to the post page. This checks for a custom field called ‘noFeature’. If it’s there then the image isnt displayed.
templates/blogpost/single-cover-layout.php : line 24-29 now looks like this:
i just add noFeature=true as a custom field and i can have a featured image on the home page without one on the blog bost. of course, this is just for the COVER template so edit the one you need.
