Thanks, now I understand. Any suggestions as to where the the <div> should start? This doesn’t seem to work:
<?php
if (have_posts()) :
while (have_posts()) : the_post(); ?>
<div class="posticonbox" id="posticonbox">
<?php if (function_exists('get_cat_icon'))
get_cat_icon('fit_width=50&fit_height=50&small=true&class=reflect');
?>
</div>
