grabing the attachment from post

hello there.. currently, I am creating a template that will display the post based on the category..
this is my way of calling the latest post from the category..

<article id = "featuredarticle">
				<?php $my_query = new WP_Query('category_name=featured article&posts_per_page=1');
				while ($my_query->have_posts()) : $my_query->the_post();
				$do_not_duplicate = $post->ID; ?>
				<h2><?php the_category();?><h2>
				<h3><a STYLE="text-decoration:none"href = "<?php the_permalink();?>"><?php the_title();?></a></h3>
					<p>
						<?php the_excerpt();?>
					</p>
					<?php endwhile; ?>
					<a href = "#"><img src="http://localhost/wordpress/wp-content/uploads/2011/10/featuredarticle.png" alt="Featured Article"/></a>
			</article><!--End of Featured Content-->

but.. I left something… the attachment.
the attachment is can be image or video.
how can I call it?

thanks in advance..
