Featured posts with image on a static page?

Hey!

I’m trying to style an excerpt with three latest posts on a page that is set to be the homepage.
I just cant figure out how to pull the featured image. The posts has to be inline with each other with the image on top.

This is my page-frontpage.php

<?php
/*
	Template Name: Frontpage
*/
?>
<?php get_header(); ?>

</div>

			<?php while ( have_posts() ) : the_post(); ?>
				<?php get_template_part( 'content', 'page' ); ?>

			<?php endwhile; // end of the loop. ?>

<div id="main" class="wrapper">

	<article id="frontpage-featured">
		<?php
		$temp = $wp_query; $wp_query= null;
		$wp_query = new WP_Query(); $wp_query->query('cat=6&showposts=1' . '&paged='.$paged);
		while ($wp_query->have_posts()) : $wp_query->the_post(); ?>

		<h2><a>" title="Read more"><?php the_title(); ?></a></h2>
		<?php the_excerpt(); ?>

		<?php endwhile; ?>

		<?php wp_reset_postdata(); ?>

	</article>

	<article id="frontpage-kund">
		<?php
		$temp = $wp_query; $wp_query= null;
		$wp_query = new WP_Query(); $wp_query->query('cat=5&showposts=3' . '&paged='.$paged);
		while ($wp_query->have_posts()) : $wp_query->the_post(); ?>

		<h2><a>" title="Read more"><?php the_title(); ?></a></h2>
		<?php the_excerpt(); ?>

		<?php endwhile; ?>

		<?php wp_reset_postdata(); ?>

	</article>

<?php get_footer(); ?>
