Add the option for a third column on the Edit Post and Edit Page screens. This is useful if you have a lot of boxes on your edit screen, from custom taxonomies and plugins.
Also adds a pair of mini columns underneath the edit boxes, giving you space for more small boxes.

Спасибо создателю плагина. В одно нажатие задача решается этим плагином.
Есть минус: в начале кода плагина идут 2 пустых символа, что вызывает ошибки на сайте. Зайдите в код плагина и удалите их.

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.
