Description
Displays the post thumbnail.When a theme adds 'post-thumbnail' support, a special 'post-thumbnail' image size
is registered, which differs from the 'thumbnail' image size managed via the
Settings > Media screen.
When using the_post_thumbnail() or related functions, the 'post-thumbnail' image
size is used by default, though a different size can be specified instead as needed.
