Need help with some PHP code

I hope I’m posting this in the right place. One of my clients had someone built him a custom wordpress theme, but the original designer didn’t add the finishing touches. I’m stuck on some php coding that I can’t figure out. One the home page http://chuckwardrealestate.com/ you’ll see the featured properties section. This is the code calling this featured properties box:

[ Code edited with backticks. Moderator note: when sharing code examples, please wrap the code in backticks or use the code button. ]

<div class="bordercontent"><h2> Featured Properties </h2></div>

			<div class="topleftimagecontent">

			<?php query_posts('cat=4&posts_per_page=6');
			if (have_posts()) : while (have_posts()) : the_post(); ?>
			<div class="topFeaturedimage">
			  <div class="Featuredimage"><?php the_post_thumbnail();?></div>
			  <div class="Featuredtitle"> <p> <?php the_title(); ?></p></div>
			</div>
			<?php endwhile; endif; ?>
			<?php wp_reset_query(); ?>
		</div>
	</div>
</div>

The appearance is fine, but I need to add functionality. What I want to happen is to make the images clickable so that you can go to the posts where the images are. I don’t know enough about php to write this code. Can anyone help me with this?
