page_data->get_the_post_thumbnail

Hello!

I am creating a One page Design in WordPress. I can include the page content and title in the index with the following code:

<div id="column3"><!-- Start Column3 -->
                        <?php
						$page_id = 5;
						$page_data = get_page( $page_id );
						?>
                        <h2><?php echo $page_data->post_title; ?></h2>
                        <?php echo $page_data->get_the_post_thumbnail; ?>
                        <p><?php echo $page_data->post_content; ?></p>
                    </div><!-- End Column3 -->

Only, the featured image doesn’t get loaded in. Is there another method to make it work?

I’ve added the following code into my Functions.php:

<?php
add_theme_support('post-thumbnails', array('page'));
?>
