Im trying to change my header from the php default to a html image with hot spots linking to parts on and off site.

I tried editing tpl_header.php by replacing the logowrapper code but have had no success

here is the code I want to put in, I just cant figure out were to put it :)

<img src="header_bg.JPG" width="978" height="160" border="0" usemap="#Map" />
<map name="Map" id="Map"><area shape="rect" coords="11,7,448,157" href="http://www.thegoffshop.co.uk" target="www.thegoffshop.co.uk" />
<area shape="rect" coords="539,13,644,43" href="http://thegoffshop.co.uk/index.php?main_page=shopping_cart" />
<area shape="rect" coords="661,14,761,42" href="http://www.myspace.com/thegoffshop" />
<area shape="rect" coords="779,14,874,43" href="#" /><area shape="rect" coords="892,13,966,43" href="http://thegoffshop.co.uk/index.php?main_page=login" />

the template im using is Mihluna

Thanks in advance
