How to disable user pictures in teasers of a content type

Hi-

So I have a unique tpl file made for a "blog" content type. I have user pictures enabled for this content type, but I would like to alter the tpl file so that user pictures ONLY show up on the body, NOT in the teaser. Can someone please show me how the following tpl php code has to be altered to exclude user pictures from teasers ONLY?

thanks so much,

<div class="node<?php if ($sticky) { print " sticky"; } ?><?php if (!$status) { print " node-unpublished"; } ?>" id="node-<?php print $node->nid; ?>">
  <?php if ($page == 0): ?>
    <h2 class="title">
      <a href="<?php print $node_url ?>"><?php print $title ?></a>
    </h2>
  <?php endif; ?>

  <?php if ($picture) print $picture ?>  
  
  <?php if ($submitted or $has_terms): ?>
  <div class="meta<?php if ($has_terms) : ?> with-taxonomy<?php endif; ?>">
  
    <?php if ($submitted): ?>
      <div class="submitted"><?php print t('Posted ') . format_date($node->created, 'custom', "F jS, Y") . t(' by ') . theme('username', $node); ?></div> 
    <?php endif; ?>
       
  </div>
  <?php endif; ?>
  
  <div class="content">
    <?php print $content?>
  </div>
  
  <?php if ($links): ?>
    <div class="links">
      <?php print $links ?>
    </div>
  <?php endif; ?>
  
</div>
