correcting with proper image path_to_theme and theme_image bug

RSS icon on page.tpl does not show up, below is the Drupal 6 way
http://api.drupal.org/api/function/path_to_theme/5
http://api.drupal.org/api/function/theme_image/5

on page.tpl.php line 20+
change

<?php if ($is_front) { ?><span id="rss"><a href="<?php print url('rss.xml', array('absolute' => 'true')) ?>"><img width="14" height="14" src="/<?php print $directory ?>/images/rss.png" /></a></span><?php } ?>

to

<?php if ($is_front) { ?><span id="rss"><a href="<?php print url('rss.xml', array('absolute' => 'true')) ?>"> <?php print  theme('image', path_to_theme() .'/images/rss.png');
?> </a></span><?php } ?>

hope it helps
