我正在使用add_theme_support( \'custom-header\', $defaults ); 在我的主题中支持自定义标题图像。这个$defaults 中介绍了Custom Headers 文章

$defaults = array(
    \'default-image\'          => \'\',
    \'random-default\'         => false,
    \'width\'                  => 0,
    \'height\'                 => 0,
    \'flex-height\'            => false,
    \'flex-width\'             => false,
    \'default-text-color\'     => \'\',
    \'header-text\'            => true,
    \'uploads\'                => true,
    \'wp-head-callback\'       => \'\',
    \'admin-head-callback\'    => \'\',
    \'admin-preview-callback\' => \'\',
);
