2 headers? Quick question

With the help of Tyler from ontherocks comics, I’ve added this to my header.php for my theme and gotten the comics above the news.

<?php
$gposts = get_posts(‘numberposts=1’);
foreach ($posts as $post) :
?>

<?php echo ‘<img src=”‘ ?>
<?php the_time(‘Y-m-d’) ?>
<?php echo ‘.gif”/>’ ?>

<?php
endforeach;
?>

My only issue now is, I’d like the images to only show for the news posts, not new pages. If I post a page today that doesn’t have a comic it shows a red x, because it’s looking for comic with todays date, I’d like to have a seperate header for pages that doesn’t include the php above, but unsure how to use 2 different headers.
