Node images alongside the articles

I'm trying to add node image images alongside the article teasers. Its suppose to lool like this:
http://santoro.ic.cz/image-node.jpg
I only know I should use this piece of code

<div class="ikona_clanku">
<a href="<?php print $node_url; ?>"><?php print $node->node_images; ?></a>
</div>

and add it somewhere to node.tpl.php:

<?php phptemplate_comment_wrapper(NULL, $node->type); ?>

<div id="node-<?php print $node->nid; ?>" class="node<?php if ($sticky) { print ' sticky'; } ?><?php if (!$status) { print ' node-unpublished'; } ?>">

<?php print $picture ?>

<?php if ($page == 0): ?>
  <h2><a href="<?php print $node_url ?>" title="<?php print $title ?>"><?php print $title ?></a></h2>
<?php endif; ?>

  <?php if ($submitted): ?>
    <span class="submitted"><?php print t('!date — !username', array('!username' => theme('username', $node), '!date' => format_date($node->created))); ?></span>
  <?php endif; ?>


  <div class="content">
    <?php print $content ?>
  </div>

  <div class="clear-block clear">
    <div class="meta">
    <?php if ($taxonomy): ?>
      <div class="terms"><?php print $terms ?></div>
    <?php endif;?>
    </div>

    <?php if ($links): ?>
      <div class="links"><?php print $links; ?></div>
    <?php endif; ?>
  </div>

</div>

But I am not experieced enough to know know how should I place it here to achieve this look: http://santoro.ic.cz/image-node.jpg (article image ALONGSIDE the article)
Can somebody give me some advice? Thanks :-)
