Feat image link to page url ??

Hi

I’m trying to get a child theme working, and are having promblems with function.php, and getting teatured image to link to the page url ..

<?php
function hent_pages(){

	$args = array(
		'sort_order' => 'ASC',
		'post_type' => 'page',
		'sort_column' => 'menu_order'
	);

	$pages = get_pages($args);

	foreach ($pages as $page) {
		if($page->post_parent == 0){
                        echo '<div class="polaroid">';

			//echo $page->post_title . "<br>";

                        $feat_image = wp_get_attachment_url( get_post_thumbnail_id($page->ID) );
			echo '<div class="polaroidimage"><a href="" rel="bookmark"><img src="'.$feat_image.'"></a>';
			echo '<div class="polaroidtitle">hej<br></div>';
                        echo '</div></div>';

		}
	}
}
?>

It’s the a href i need to transform into php, and i can’t figure out how to do it, maybe i’ve bin sitting to many hours behind the screen, so i’m not thinking that clear anymore ??

Thanks
