the changes that i have done on K2 are on the templates..

components/k2/templates/default/category_item.php on line 234..

i commented out the original code <?php echo $this->item->gallery; ?> and added my code..

<!-- FreakShowTM mod start -->
<?php $oldtext = $this->item->gallery; ?>
<?php $newtext = JHTML::_('content.prepare', $oldtext, $params); ?>
<?php echo $newtext; ?>
<!-- FreakShowTM mod end -->
