Is there a way to show a banner in the header only on the front page?

should be possible by wrapping the code of the div .slogan into a conditional statement using is_front_page() or is_home() :

edit the template file that displays the front page (usually index.php) and do something like:

<?php if(is_front_page || is_home() ) : ?>
<div class="slogan">
					<div class="indent"><h2><img alt="" ...(...php code....)...a></p></div>
				</div>
<?php endif; ?>

and also edit header.php and add the following, before </head>

<?php if(is_front_page || is_home() ) : ?>
<style type="text/css" media="screen">
.header { height:219px;}
</style>
<?php endif; ?>

adjust the height to get the design you want.

Thanks. I’ll try it.
