Adding image in results search.php

I want my search results to show an image of the product. Currently the search results only show a text link. My wordpress theme is Intuition Pro

<?php get_header(); ?>

<div id="main" class="main">
	<div class="container">
		<section id="content" class="content">
			<?php do_action('cpotheme_before_content'); ?>
			<?php if(have_posts()): while(have_posts()): the_post(); ?>
			<article class="search-result" id="post-<?php the_ID(); ?>"> 			
				<h4 class="search-title heading">
					<a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>" rel="bookmark"><?php the_title(); ?></a>
				</h4>
				<div class="search-byline">
					<?php the_permalink(); ?>
				</div>
			</article>
			<?php endwhile; ?>
			<?php cpotheme_numbered_pagination(); ?>
			<?php endif; ?>
			<?php do_action('cpotheme_after_content'); ?>
		</section>
		<?php get_sidebar(); ?>
	</div>
</div>

<?php get_footer(); ?>

The page I need help with: [log in to see the link]
