Adds a [post_thumbnail] shortcode for use with wordpress post thumbnails. Size can also be set using [post_thumbnail size=”XXXX”]. (You can call the function directly in your theme with <code><?php post_thumbnail('size=thumbnail');?></code>.)
Just insert the shortcode into any post’s content and when it will be replaced with the featured image.
This works only with the featured images introduced in WordPress 2.9.
