Get featured image

I need little help with getting featured image.

I’m using Pods Plugin and I made my Pod as Post type. Now I want to display Pods title, content and featured image. My code look like this:

<?php
$mypod = pods(‘program’);
$mypod->find(‘name ASC’, $limit);
$limit = 1000;
$counter = 1
?>
<?php while ( $mypod->fetch() ) : ?>
<?php
// set variables
$title= $mypod->field(‘title’);
$description= $mypod->field(‘content’);
$featureimg= $mypod->field(‘post-thumblines’);
?>
<?php echo $title; ?>
<?php echo $description; ?>
<?php echo $featureimg; ?>
<?php endwhile; ?>

From this code I’v got my title and content but not featured image. Can somebody help me how to get Featured image PLEASE!

Thanks!
