I’m using this code for displaying posts:

get_header(); ?>
<img width="980" height="800" src="http://www.verstijlenhekwerken.nl/new/wp-content/uploads/2012/02/DSC_0027-980x800.jpg" class="bg wp-post-image" alt="DSC_0027" title="DSC_0027" />
	<div class="content">
        <?php get_sidebar("filter"); ?>
        <div class="archive">
        	<h1>Projecten</h1>
            <hr class="title" />
<?php
if ( have_posts() ){
	while ( have_posts() ) : the_post();
		echo "<div class='thumb'>";
		$parameters = array('output' => 'html','size' => 'thumbnail');
		echo(types_render_field('afbeelding', $parameters));
		echo "</div>";
 	endwhile;
}
?>
			<hr class="bottom" />
            <div class="navigation">
                <?php previous_posts_link('Volgende') ?> | <?php next_posts_link('Vorige') ?>
            </div>
		</div>
     </div>
<?php get_footer(); ?>
