<!--Bof creinold Pinterest .) -->
<div id="pinterest"><a href="http://pinterest.com/pin/create/button/?url=<?php echo zen_href_link(FILENAME_PRODUCT_INFO); ?>&media=<?php echo HTTP_SERVER . DIR_WS_CATALOG . $products_image_medium; ?>&description=<?php echo stripslashes($products_description); ?>" class="pin-it-button" count-layout="horizontal">Pin It</a></div>
<script type="text/javascript" src="//assets.pinterest.com/js/pinit.js"></script>
<!--eof creinold Pinterest .) -->
