Duplicate Categories

Hi

I have put up my site the link to it is
http://www.ispysurf.com

You will be able to see on the post thumbnails that all the category images are being assigned to every post regardless of what categories were actually selected.

This has something to do with the code in the loop. Any ideas how to fix it?

Thanks C

<div class="content-container loop-container">

	<?php if ( have_posts() ) : ?>

		<div class="wrapper">

			<?php /* Start the Loop */ ?>
			<?php while ( have_posts() ) : the_post(); ?>

				<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
					<a href="<?php the_permalink() ?>"><h2 class="entry-title"><span>
						<?php echo get_the_title() ? get_the_title() : __('Untitled', 'focus') ?>

					</span></h2></a>

           <strong> <?php foreach (get_categories() as $cat) : ?>        

 <div class=cat_images>

 <img src="<?php echo z_taxonomy_image_url($cat->term_id); ?>" />
 <a href="<?php echo get_category_link($cat->term_id); ?>"></a>

 </div>
 <?php endforeach; ?></strong>
 <div class="clear"></div>

  <a href="<?php the_permalink() ?>" class="thumbnail-wrapper">
						<!-- <div class="time"></div> -->
						<?php echo has_post_thumbnail() ? get_the_post_thumbnail() : focus_default_post_thumbnail();  ?>

					</a>
				</article>

			<?php endwhile; ?>

		</div>

	<?php else : ?>

		<?php get_template_part( 'no-results', 'index' ); ?>

	<?php endif; ?>

	<div class="clear"></div>

</div>

<?php focus_content_nav( 'nav-below' ); ?>
