Answer 1

Use the following code to avail the thumbnail image in the Magento:

$Media = $product->getMediaGalleryEntries();
foreach ($Media as $image) {
    $image->getTypes();
}

getTypes() returns an array that may contain the following vlaues:

• image
• small_image
• thumbnail

If it contains thumbnail then it's the thumbnail image.
