Adding Graphic Image/Script Element on Left/Right Column

[BlessIsaacola]

I am trying to add some sales graphics on the right and left columns as well as livehelp graphic icon. I do not want this images in a sidebox. I tried to do it and it appears to work but I am not sure if this is the right way/code to achieve what I am trying to do. Please take a look at the code below to see what I have done. I copied a whole section from the tpl_main_page.php so you can see my change.

You can see the result of this code at clevershoppers.com/zctest/ on the right side below the last sidebox. Please help me do this the right way :)

/**

?>
<div id="navColumnTwoWrapper" style="width: <?php echo BOX_WIDTH_RIGHT; ?>"><?php require(DIR_WS_MODULES . zen_get_module_directory('column_right.php')); ?></div><a href="http://www.clevershoppers.com/music-rock-c-9_40.html">
<img border="0" src="/images/top_rock2.jpg" width="164" height="49"></a><br /><br /><script type="text/javascript" src="https://clevershoppers.com/livehelp/livehelp_js.php?relative=Y&amp;department=1&amp;pingtimes=15&amp;secure=Y"></script></td>
