 * Hi
    I have developed a very simple WordPress theme but I have problem with **
   thumbnails** or featured image for my custom post types. I have added below codes
   to my _function.php_ file for theme support of thumbnails, but yet have problem
   with the custom post type’s thumbnails. what is the problem? Thanks
 * `add_theme_support('post-thumbnails');`
 * and also
 *     ```
       function custom_theme_setup() {
           add_theme_support( 'post-thumbnails', array('portfolio'));
       }
       add_action( 'after_setup_theme', 'custom_theme_setup' );
       ```

 * Taken from quick search of the forums:
 * >     ```
   >     'supports' => array( 'title', 'editor', 'comments', 'excerpt', 'custom-fields', 'thumbnail' ),
   >     ```
   > 
   > when registering your custom post type, you must add the thumbnail support.
   > Here is an example from my supports line, adding my required items to my CPT
 * Just be sure to add `thumbnail` to the list of supported things when you register
   the post type.
