Custom Field Suite　で　フルのurl付　これは回りくどいか？

 <!--シンプルライトボックス用rel-->
<a rel="slb slb_group[111111]" href="
<?php //イメージFULL URLを取得
$d_url = wp_get_attachment_image_src(get_post_meta($post->ID,"jirei_gazou",true),full);
echo $d_url[0];
?>
">
<?php
$title= get_the_title();
echo wp_get_attachment_image(get_post_meta($post->ID,"jirei_gazou",true),array(330,500),array('alt'=>$title,'title'=>$title)); ?>

</a>
