RobbieB1953 on "[Theme: Twenty Fourteen] Header image on main page only"

How do I have an image in the header on only one page? This is what I have:

<div id="page" class="hfeed site">
	<?php if ( get_header_image() ) : ?>
	<div id="site-header">
		<a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home">
			<img src="<?php header_image(); ?>" width="<?php echo get_custom_header()->width; ?>" height="<?php echo get_custom_header()->height; ?>" alt="">
		</a>
	</div>
	<?php endif; ?>
