有没有办法更新我的新商店视图上的所有图像以使用默认商店视图主图像？

require_once 'abstract.PHP';

class Attach_Default_Store_Images Extends Mage_Shell_Abstract {

    public function run()
    {
        $products = Mage::getModel('catalog/product')->getCollection();
        foreach ($products as $product) {
            $productFrom = $product->setStoreId(1)->getImage();
            $productTo = $product->setStoreId(13)
            ->setImage($productFrom)
            ->setSmallImage($productFrom)
            ->setThumbnail($productFrom);
            echo "Images Updated\n";
            $product->save();
   }

        Mage::getModel('catalog/product_image')->clearCache();
        echo "Image Cache Cleared\n";

    }


    public function usageHelp()
    {
        return <<<USAGE

}

$shell = new Attach_Default_Store_Images();
$shell->run();

运行上面的shell脚本？
