macmail html signature

Can someone pleeeeease help....? I have been trying to create a html email in mail mail for what seems like forever. The majority of the signature is one image with maps to different urls. The signature looks fine in the mail preferences when in mammal, but when I open a new message the signature displayed as a blue question mark.
Here is my coding...I WOULD REALLY APPRECIATE any help....

<div id="links" style="height: 20px; line-height: 17px; text-align: right;font-family: 'Lucida Grande', Verdana, Arial, Sans-Serif; font-size: 11px; color: #000; width: 600px; " >

<map name="Map" id="Map">
<area shape="rect" coords="596,38,654,58" href="#" />

The trouble with a signature using modern web standards is that it will not work as soon as you send it to anybody using Outlook
