This is the launch of the new site. There is a picture of President Barack Obama speaking at a conference honoring various members of the United States Army. The picture is only here to illustrate the theme’s capabilities surrounding a post’s featured image. This post has the photo set as the featured image but also is contained within the post.
It’s not necessary to embed the image within the post. The featured image will still display next to the post when the post is listed on a page, either for a category listing, tag, or archive.
