You should have received some code from Klipmart that looks like the following:
<script language="javascript">var obs_clk='__YOUR__CLICK__URL__';</script>
<script language="javascript" type="text/javascript" src="http://gfx.klipmart.com/klipmart/campaigns/xyz001/a/xyz001_47560.js">
</script>
<noscript>
<img src="http://kt4.kliptracker.com/klipinsert4.gif?campid=47560&ktaction=2&ad_id=1" border=0 width=1 height=1>
<a href="http://kt4.kliptracker.com/klipinsert4.tux?campid=47560&ktaction=100&ad_id=1&redir=http://www.example.com/" target="_blank">
<img src="http://gfx.klipmart.com/klipmart/campaigns/xyz001/a/xyz001a_still.jpg" border=0 width=300 height=250 alt="Example">
</a>
</noscript>
What you need to do is modify the URLs in the <SCRIPT> and <A> tags like this:
<script language="javascript">var obs_clk='%%CLICKTAG%%';</script>
<script language="javascript" type="text/javascript" src="http://gfx.klipmart.com/klipmart/campaigns/xyz001/a/xyz001_47560.js">
</script>
<noscript>
<img src="http://kt4.kliptracker.com/klipinsert4.gif?campid=47560&ktaction=2&ad_id=1" border=0 width=1 height=1>
<a href="%%CLICKLINK%%http://kt4.kliptracker.com/klipinsert4.tux?campid=47560&ktaction=100&ad_id=1&redir=http://www.example.com/" target="_blank">
<img src="http://gfx.klipmart.com/klipmart/campaigns/xyz001/a/xyz001a_still.jpg" border=0 width=300 height=250 alt="Example">
</a>
