I Can get it to show up, but only in the middle of the page.
With this:
text from sitelock = text with strikethrough
<!-- Footer -->
<!--sitelock icon-->
<a href="https://www.sitelock.com/verify.php?site=MY URL" target="_blank"><img alt="website security" title="SiteLock" border="0" src="//shield.sitelock.com/shield/MY URL"/></a>
<!-- end of sitelock icon-->
<div id="footer">{$HOOK_FOOTER}</div>
</div>
{/if}
</body>
</html>
