cath_image function causing blank pages

  • For some reason, the function below in my functions.php in theme folder seems to cause blank pages on saving anything in the admin section. Anyone got a idea what is causing this problem?

    <?php
function catch_image() {
	global $post, $posts;
	$first_img = '';
	ob_start();
	ob_end_clean();
	$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
	$first_img = $matches [1] [0];
	if(empty($first_img)){
	$first_img = "/images/default.jpg";
	}
	return $first_img;
	}
?>

    i just placed a else on the bottom and now it seems to work, but it couldn’t be that ??

    dunno, i am happy

    function catch_that_image () {
	global $post, $posts;
	$first_img = "";
	ob_start();
	ob_end_clean();
	$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
	$first_img = $matches [1] [0];
	if(empty($first_img)){
	$first_img = "/images/default.jpg";
	} else {
	return $first_img;
	}
	}
