How do I replace a featured image with another image or video?
Usage
You can now hide the Featured Image on a post or page using the <!--masthead--> tag at the top of your page or post. Place <!--masthead--> at the top of your post or page in the html mode of the text editor window. You can also use the tag to replace the featured image with another image or video by placing the image or video iframe, or LUX Vimeo shortcode reference above the <!--masthead--> tag.
