Insert HTML with mouseover names into Outlook 2007 email

I am new to this site and hoping for some help. I have Office 2007, Adobe Photoshop CS2, along with its companions ImageReady CS2 and LiveCycle Designer ES 8.2. Running o/s Windows XP Pro ver. 2002 SP3.

I have a photo of a group of individuals and the names of those in the photo. Using Photoshop and ImageReady, I created an image map with mouseover names of the people; the document saved as an HTML file.

I can open the file and the mouseover works great, but of course, it opens in Internet Explorer. The problem is that my manager wants the photo below the signature on some, but not all, emails that are sent. He wants people to be able to hover over a person on the photo and see who it is. I have tried inserting the photo in any number of ways in an email message but cannot get the mouseover to work.

Any ideas or suggestions would be very helpful.

Thanks,
