How to hide empty custom field – post meta

  • Hi,
    I want to hide a custom field when it’s empty. In the theme I’m using it is built like below:

    <?php

if (have_posts()) : while (have_posts()) : the_post();

	$image_thumb = get_post_meta(get_the_ID(), 'blog_thumb_image_url', true);
?>

<div class="post_img">
<img src="<?php echo get_bloginfo( 'stylesheet_directory' ); ?>/timthumb.php?src=<?php echo $image_thumb; ?>&h=300&w=600&zc=1" alt="" />
							</div>

    I thought to move the <img> in the php function with an echo but really don’t know how to do…Anyone knows it?
