Create Image Map on Existing External Style Sheet

I'm not sure whether this is possible, but if so, I'm looking for someone able to add an image map to a background-image on an external style sheet. The background image is as follows on the style sheet: .header {height: 75px; text-align: right; padding-right: 10px; font-size: 90%; background-image: url(images/[login to view URL]) On the web page itself, .header is as follows: <td colspan="2" class="header"><!--webbot bot="Include" U-Include="includes/[login to view URL]" TAG="BODY" startspan --> We've had a request to make the logo, appearing in the upper right-hand corner of our humane society's website, a hyperlink to the home page. I'm not sure how to do this, but if someone is interested in accepting the job, I could provide a link to this site, which is currently under construction, along with whatever else might be necessary to complete the job. Thank you.
