kernmedia on "How to Only Show Header Image on Home Page?"

Hey Everyone, I'm using the MesoColumn theme, and it has a feature to add a header image. I only want it to show on the home page, however. Can anyone tell me how to modify this code in the header.php file to achieve that?

<?php if( get_header_image() ): ?>
<div id="custom-img-header"><img src="<?php echo header_image(); ?>" alt="" /></div>
<?php endif; ?>
