How to show featured image custom post type?

[Divvy]

Hello guys,

Can someone please give me a little help here?

I need to show a custom post type feature image in my single.php.

I am trying this code:

<?php the_post_thumbnail('freeGallery', array('class' => 'imgthumb')); ?>

But without success...
It shows the post (single.php) featured image and not the custom post (freeGallery) featured image.

What Im doing wrong? :P

Thanks!!

This is my code, but isn't working... Is only showing the post featured image and not the custom post type featured image.
Can someone tell me what I'm doing wrong?

<?php
$loop = new WP_Query(array('post_type' => 'freeGallery', 'post_status' => 'publish'));
?>
<td><div class="gallerycontainer">
<a class="bestthumbnail" target="_blank" title="<?php echo $post_title; ?>" href="<?php echo get_post_meta($ID,'mr_freeGalleryUrl',true); ?>" rel="nofollow"><?php $title = $post_title; if (strlen($title) > 85){ echo substr($title,0,85).'...';}else { echo $title;}?><span><?php the_post_thumbnail('freeGallery', array('class' => 'imgthumb')); ?></span></a></div></td>

Thanks

<?php
$loop = new WP_Query( array( 'post_type' => array('freeGallery')&'post_status=publish'));
if ( $loop->have_posts() ) : $loop->the_post(); ?>
<div><?php echo the_post_thumbnail(); ?></div>
<?php endif; ?>
