How to Add Featured Image Support to your WordPress Theme

If your WordPress dashboard is not displaying a “Featured Image” screen section when adding or editing a post, it might be that your theme does not support the Featured Image function.

To fix that problem, you can edit your theme’s functions.php file and add the following line:

add_theme_support( 'post-thumbnails' );

For more information on the WordPress Featured Image function, see Featured Images & Post Thumbnails on the WordPress.org website.
