Provides a shortcode for embedding post-thumbnails. Authors can quickly change pictures in posts without wading through HTML. This can be awesome in several ways: if your post-thumbnails change the width or height due to a theme change, or if you have cropped them with another tool — this will always pull wordpress’ latest image).
Includes a hook into the media library to create the above shortcode.
Add new post thumbnails via WordPress Settings → Media.
