aşağıdaki gibi hocam

<?php get_header(); ?>


<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
		
<div id="post-<?php the_ID(); ?>">


<a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php
if ( has_post_thumbnail() ) { ?>
	<img class="postimg" src="<?php bloginfo('stylesheet_directory'); ?>/timthumb.php?src=<?php get_image_url(); ?>&amp;h=86&amp;w=159&amp;zc=1" alt="" />
<?php } else { ?>
	<center><img class="postimg" src="<?php bloginfo('stylesheet_directory'); ?>/timthumb.php?src=<?php bloginfo('template_directory'); ?>/images/dummy.jpg&amp;h=86&amp;w=159&amp;zc=1" alt="" /></center>
<?php } ?></a>






<?php endwhile; ?>
<?php getpagenavi(); ?>
<?php else : ?>
	<h1 class="title">Bulunamadı</h1>
	<p>Aradığınız sayfa kaldırılmış.</p>
<?php endif; ?>
</div>

<?php get_footer(); ?>

Çeken kod aşağıda koyu renkle belirttiğimdir

<a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php
if ( has_post_thumbnail() ) { ?>
<img class="postimg" src="<?php bloginfo('stylesheet_directory'); ?>/timthumb.php?src=<?php get_image_url(); ?>&amp;h=86&amp;w=159&amp;zc=1" alt="" />
<?php } else { ?>
<center><img class="postimg" src="<?php bloginfo('stylesheet_directory'); ?>/timthumb.php?src=<?php bloginfo('template_directory'); ?>/images/dummy.jpg&amp;h=86&amp;w=159&amp;zc=1" alt="" /></center>
<?php } ?></a>

sonrada css den postimg classına float:left; ekledim resimlerde yanyana dizildi, film sitelerinde olduğu gibi gece gece biraz yordu ama oldu.
