PHP - URL Image module

[ronymac]

Hello I'm doing a module to generate XML for the Rocket, using the basic Google Base is now missing only the last step when I put the parameters used for the image, it does not work. Already activated and took the friendly url.

<?php

class googlemerchant extends Module{

   private $_html = '';
   private $_currLID;
   private $_host;
   private $_feedDescription;
   private $_baseUrl, $_directory, $_filename, $_filename_http;

   public function __construct(){
	global $cookie;
	
	$this->name = 'googlemerchant';
	$this->_currLID = intval($cookie->id_lang);
	
	$this->_host = $_SERVER['HTTP_HOST'];
	
	parent::__construct();
	
	$this->tab = 'seo';
	$this->version = '0.1';
	$this->page = basename(__FILE__, '.php');
	$this->displayName = $this->l('Google XML -  Por Imaginare Digital');
	$this->description = $this->l('Google XML -  Por Imaginare Digital | [email protected]');
	
	$this->_baseUrl = __PS_BASE_URI__;
	$this->_directory = dirname(__FILE__).'/../../';
    	$this->_filename = $this->_directory.strtolower(Language::getIsoById($this->_currLID)).'_googlebase.xml';
