How to get all gallery image with resize of a product in magento

In product page you can get gallery image of the current product, But if you think to fetch all gallery image of a product in other page like cms page, then you have to write the code with little bit modification. The code should looks like below

load($id);
// 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
echo "url)." alt='' />";
//For gallery Image
$resizeimage = $obj->helper('catalog/image')->init($_product, 'thumbnail', $_image->getFile())->backgroundColor(242,242,243)->resize(400,300);
echo "";
}
} 

Hope it Helps... Thanks....
