Resizing magento gallery images

i am trying to display product gallery images in my custom cms home page. If i use the code from media.phtml to display the gallery images, it does not work. I found this piece of code and it worked.

<div id="thumbs" class = "thumbs-home">
    <?php 
        $obj = new Mage_Catalog_Block_Product_View_Media();
        $_product1 = new Mage_Catalog_Model_Product();
        // Load all product information of a particular product
        $Products_one = Mage::getModel('catalog/product')->load($productId);
        // Use your Product Id instead of $id
        $countt = count($Products_one->getMediaGalleryImages());
        if($countt>0){
        foreach ($Products_one->getMediaGalleryImages() as $_image)
        {
        // For the Original Image
        $thumb_img = "<img src=".Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_MEDIA).str_replace(Mage::getBaseUrl('media'),"",$_image->url)." alt=''width='60' height='60' />";
        echo "<a href='".Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_MEDIA).str_replace(Mage开发者_Go百科::getBaseUrl('media'),"",$_image->url)."'rel='lightbox[gallery]'>".$thumb_img."</a>";      
        //For gallery Image
        //$resizeimage = $obj->helper('catalog/image')->init($_product, 'thumbnail', $_image->getFile())->backgroundColor(242,242,243)->resize(400,300);
        //echo "<img src=".$resizeimage."alt='' />";
        }
        } 
    ?>

This gets the actual images and gets resized by the width and height attributes. But i want to resize the image through magento. The last piece of code $resizeimage is not working for some reason. How can i make this work? The problem is that i am using a lightbox to display the gallery images which displays the actual high resolution images that are too large. The light box takes in width and height of image provided and i am not able to figure out as to how i set a standard dimensions for the light box. So the only other option is the have the images resized by magento before passing them to the lightbox. Thanks.

You just need to call proper object, instead of $obj->helper you should use Mage::helper, so your call should look like this:

print Mage::helper('catalog/image')
 ->init($product, 'thumbnail', $image->getFile())
 ->backgroundColor(255,255,255)
 ->resize(100,100);

And that's it! :)
