 = Scenarios

 A post has a post format of Image, but the current theme does not support
 the Image post format but:
 - There's a gallery shortcode in the content and you want the first image
 - There are images attached to the post and you want the first one
 - There is an image tag as the content or in the content and you want the
 src
 - The content is a URL representing an image
 - The content is a URL representing an image, followed by new line(s),
 followed by commentary

 Introduce `the_image()`, `get_the_image( $post_id = 0 )`,
 `get_content_image( &$content, $remove = false )`, `get_post_images(
 $post_id = 0 )`
