如何在Magento的浏览器上显示图像

Question

      <?php
            $hint = 'dell';

            $sql="SELECT p.`entity_id`, pv.`value` as name, 
                     GROUP_CONCAT(DISTINCT(pm.`value`) SEPARATOR ', ') as imagesPath
                   FROM `catalog_product_entity` as p
                   INNER JOIN `catalog_product_entity_varchar` as pv 
                     ON pv.`entity_id` = p.`entity_id` and  pv.`attribute_id` = 71
                   LEFT JOIN `catalog_product_entity_media_gallery` as pm 
                     ON pm.`entity_id` = p.`entity_id` and pm.`attribute_id` = 88
                   WHERE pv.value LIKE '".$hint."'";

            foreach($readConnection->fetchAll($sql) as $orders) {
    ?>

    <img src="<?php echo Mage::getBaseUrl('media').'catalog/product'. $orders["imagesPath"].''; ?>" alt="" />

    <?php
        }
    ?>

此代码的输出是

<img src="http://127.0.0.1/magento/media/catalog/product/2/_/2.jpg" alt="" />

它只显示了图像的路径，但我希望在浏览器的输出中显示图像。
