Ram, hello and welcome to our forum 
With this design is bad, because you will need to change banner in all templates manually
Quote
<!-- <header> -->
<table border="0" cellpadding="2" cellspacing="0" width="100%" height="124" style="border-bottom:1px solid #988675;">
<tr><td align="right" style="background:url('
/.s/t/986/3.jpg') no-repeat;padding-right:100px;"><span style="color:#FFFFFF;font:16pt bold Verdana,Tahoma;">SITE LOGO</span></td></tr>
</table>
So, to change logo/banner change this link to your banner link
