#2 Removing a Feature In a Child Theme

In some cases, a Parent Theme may have activated a feature that you do not want to have available in your Child Theme. For instance, if you are using a parent theme that has activated Featured Images for all Pages and Posts, but you’d like to remove the functionality of having Featured Images for Pages in your Child Theme, you could do something like this:

// in your Child Theme's functions.php    

// Use the after_setup_theme hook with a priority of 11 to load after the
// parent theme, which will fire on the default priority of 10
add_action( 'after_setup_theme', 'remove_featured_images_from_child_theme', 11 ); 

function remove_featured_images_from_child_theme() {

	// This will remove support for post thumbnails on ALL Post Types
	remove_theme_support( 'post-thumbnails' );

	// Add this line in to re-enable support for just Posts
	add_theme_support( 'post-thumbnails', array( 'post' ) );
}
