You need to predefine the variables before you use them. For $images it would be

$images = array();

right after if (!empty($url)) { etc

if (array_key_exists('images', $data)) {    // display the image    }else{    //set a default image, etc}

you can suppress errors by using the @ symbol. i.e.

 @     $data['images']     = $images;
