I want to use a Featured Image for my Blog Post, so that the image is visible in the Blog Post Content Section, but I don't want that Image to also appear inside the body of my Blog Post. I don't need to see it there. Inside the body of the blog, I want to insert another image/media and have that image/media be the visual content of the blog post.
The use case is to have a Thumbnail for an embedded YouTube Video. So, the cover of the blog will have the Thumbnail of the YouTube Video. But inside the Blog post, that Thumbnail does not re-appear. Instead, users see the actual embedded YouTube video.
