Image on Author List page

Hi!

First, I would like to thank you for your work on this plugin… it is very well thought out.

I have created a author list page which shows a list of all the wordpress site authors, a description.. and an image.

I tried pasting the code provided with the plugin, but it is not displaying any images. Here is what I have so far:

<?php
/*
Template Name: Display Authors
*/
?>
<?php get_header(); ?>
<?php
// Get all users order by amount of posts
$allUsers = get_users('orderby=post_count&order=DESC');

$users = array();

// Remove subscribers from the list as they won't write any articles
foreach($allUsers as $currentUser)
{
	if(!in_array( 'subscriber', $currentUser->roles ))
	{
		$users[] = $currentUser;
	}
}

?>

<section class="content" role="main">
	<?php
		printf('<h1>%s</h1>', the_title());

		foreach($users as $user)
		{
			?>
			<div class="authorlist">
			<div class="authorlstleft">
			<h2 class="authorName"><?php echo $user->display_name; ?></h2>
			<div class="authorimagelst">
<?php
    // Retrieve The Post's Author ID
    $user_id = get_the_author_meta('ID');
    // Set the image size. Accepts all registered images sizes and array(int, int)

    // Get the image URL using the author ID and image size params
    $imgURL = get_cupp_meta($user_id, 'thumbnail');

    // Print the image on the page
    echo '<img src="'. $imgURL .'" alt="">';
?>
</div>
				</div>
				<div class="authorlstright">
					<p class="authorDescrption"><?php echo get_user_meta($user->ID, 'description', true); ?></p>
					<p class="authorLinks"><a href="<?php echo get_author_posts_url( $user->ID ); ?>">View Author Links</a></p>

					<p class="socialIcons">
						<ul>
							<?php
								$website = $user->user_url;
								if($user->user_url != '')
								{
									printf('<li><a href="%s">%s</a></li>', $user->user_url, 'Website');
								}

								$twitter = get_user_meta($user->ID, 'twitter_profile', true);
								if($twitter != '')
								{
									printf('<li><a href="%s">%s</a></li>', $twitter, 'Twitter');
								}

								$facebook = get_user_meta($user->ID, 'facebook_profile', true);
								if($facebook != '')
								{
									printf('<li><a href="%s">%s</a></li>', $facebook, 'Facebook');
								}

								$google = get_user_meta($user->ID, 'google_profile', true);
								if($google != '')
								{
									printf('<li><a href="%s">%s</a></li>', $google, 'Google');
								}

								$linkedin = get_user_meta($user->ID, 'linkedin_profile', true);
								if($linkedin != '')
								{
									printf('<li><a href="%s">%s</a></li>', $linkedin, 'LinkedIn');
								}
							?>
						</ul>
					</p>
				</div>
			</div>
			<?php
		}
	?>
</section>

<?php get_footer(); ?>

Any help would be greatly appreciated!

Thank You,
Danny
