Need to add image map code for header image.

I've created an image map for my header image. It looks like this:

<map name="Header" id="Header">
<area shape="circle" coords="750,87,43" href="stjathenaeum.kohavt.org" alt="Seach our Catalog" />
<area shape="circle" coords="890,87,44" href="ask_question.htm" alt="Ask a Question" />
<area shape="rect" coords="496,44,684,68" href="mailto:inform@stjathenaeum.org" alt="Email Us" />
</map>

I created it in Dreamweaver. The image is at http://www.stjathenaeum.org\WordPres...-images/header. I don't know PHP but from reading it would appear that I have to add the code and the image source to HEADER.PHP. I created a copy of the BFA HEADER.PHP in my child theme directory and renamed it HEADER.PHP. Where do I add all this code in the PHP file?

Any help would be wonderful. This site is in development so I'm assuming that once it is moved to its final location I'll have to edit the location of header image?

Thanks.
