Show second image of a product

[giulym]

Hello,

there is a way to show the second (or the last one) image of a product (not the main cover)? 
I found this but it isn't for the 1.7.5.1 version:
 

 public static function geImagesByID($id_product, $limit = 2){
        $id_image = Db::getInstance()->ExecuteS('SELECT `id_image` FROM `'._DB_PREFIX_.'image` WHERE `id_product` = '.(int)($id_product) . ' ORDER BY position ASC LIMIT 1, ' . $limit);
        $toReturn = array();
        if(!$id_image)
           return;
        else
           foreach($id_image as $image)
              $toReturn[] = $id_product . '-' . $image['id_image'];
        return $toReturn;
    }
