I can't find any thread 'how to insert thumbshots.com code'.
I'm running Zen Cart latest version on Apache server.

So far I understand that I have to insert these two quotes:
<img src="http://open.thumbshots.org/image.aspx?url=[LINK]" border="1" />
and
<a href="http://www.thumbshots.com" target="_blank" title="Thumbnails Previews by Thumbshots">Thumbnails powered by Thumbshots</a>
into the 'tpl_footer.php' file.

I found so far only this option
<?php

echo "<a href=\"#\" onclick=\"return false\" onmouseover=\"Tip(\'<img src='http://open.thumbshots.org/image.aspx?url=$link'\' width=\"200\" >)\" onmouseout=\"UnTip()\">";

?>
tested it, but no luck.
I am newbie in PHP, so I might wrongly edited it to replace '$link' argument with my website link.

Can anybody to direct me in the right direction please?
