Default Can CSS help with this?

I have a program that converts PowerPoint presentations to a series of HTML pages and images.

It also converts any links found on each PPT slide to working links in the HTML. It uses an image map to do this, and there's the rub. Image map wants absolute pixels for coordinates, which forces me to use pixels to specify the image size ... no way to make the layout fluid or to fill the browser window regardless of size. Image map doesn't allow %.

Here's a simplified example of what I'm doing now:

==============================================

[head/body tags]

<map name="slide_1" id="slide_1">
<area shape="rect" coords="66, 40, 320, 113" href="slide_2.HTM" title="Next Slide" />
</map>

<center><img src="slide_1.png" usemap="#slide_1" width=800 border="NO"></center><br />

[closing tags]

==============================================

Working out the relative coordinates for anything on the page shouldn't be too difficult, and given that, positioning it using CSS would follow. My problem boils down to:

WHAT do I position there?

In other words, how do I place a "something" in a div that produces a clickable link?

- Without adding anything visible to what's already there
- Without obscuring the image beneath
- And do it so that the results are accessible to e.g. screen reader users
- X-browser compatibility would be ideal, but not an overriding concern

Or is it even possible?

Any ideas welcome. Thanks!
