我正在使用儿童主题和二十三个家长。在我的子主题中创建了一个包含图像的目录。但首先要删除默认的2013主题标题。

/* Add custom headers from my child theme */

add_action( \'after_setup_theme\', \'childtheme_setup\' );

if ( ! function_exists( \'childtheme_setup\' ) ):
function childtheme_setup() {   

    /* Remove Default Headers */
    function dr_remove_twenty_thirteen_headers(){
        unregister_default_headers( array(
            \'star\',
            \'diamond\',
            \'circle\'
            )
            );
    }
    add_action( \'after_setup_theme\', \'dr_remove_twenty_thirteen_headers\', 11 );

    // Add our headers 
    register_default_headers( array(
        \'header1\' => array(
            \'url\'           => get_stylesheet_directory_uri() . \'/images/headers/target_head2.jpg\',
            //\'thumbnail_url\' => \'%s/images/headers/circle-thumbnail.png\',
            \'description\'   => _x( \'header1\', \'header image description\', \'twentythirteen\' )
        ),
        \'header2\' => array(
            \'url\'           => get_stylesheet_directory_uri() . \'/images/headers/target_head1.jpg\',
            //\'thumbnail_url\' => \'%s/images/headers/diamond-thumbnail.png\',
            \'description\'   => _x( \'header2\', \'header image description\', \'twentythirteen\' )
        ),
        \'header3\' => array(
            \'url\'           => get_stylesheet_directory_uri() . \'/images/headers/target_head0.jpg\',
            //\'thumbnail_url\' => \'%s/images/headers/star-thumbnail.png\',
            \'description\'   => _x( \'header3\', \'header image description\', \'twentythirteen\' )
        )

    ) );
}
endif;
