Featured images different for image header and thumbnail
Hi. Is there a way to specify a different featured image as the thumbnail when yo specify it as the image for the image post type? I have a set of related posts that are using the same featured images as header images, so I want to set a different one for the thumbnails. Sometimes I get this behavior all on its own, so there must be a way to configure it, but I don't see how. Can you help please?
