[Plugin: FancyBox for WordPress] how to remove css in header?

hi!

i want to remove this css code in the head, because it makes no sense to put it in the header. it belongs to the css file!:

how to remove this code:

<link rel="stylesheet" href="/wp-content/plugins/fancybox-for-wordpress/css/fancybox.css" type="text/css" media="screen" />
	<style type="text/css">
		div#fancy_inner {border-color:#333333}
		div#fancy_close {right:-15px;top:-12px}
		div#fancy_bg {background-color:#000000; border:1px solid #3f3f3f}
		div#fancy_title table {display:none}
	</style>

i tried

remove_action( 'wp_head', 'mfbfw_init' );

and this:

do_action('wpp_init', 'remove_fancybox_from_wpp');

function remove_fancybox_from_wpp() {
  wp_deregister_script('jquery-fancybox');
  wp_deregister_style('jquery-fancybox-css');
}

but BOTH do not work … i use fancybox v2.7.5

thanks in advance for your help!
