How does your content management system work?
If you simply upload a picture, then you can not make an image map. To create an image map, you must write HTML code. The HTML code for an image map looks something like this:
<img src="thelinktothepicture.jpg.jpg" border="0" />
<map name="227067249c9901ff7">
<area shape="rect" coords="154,148,339,173" href="thelinkyouwant" />
</map>
If your CMS does ot allow you to write HTML code directly, you'll need to upload a PDF, not a JPEG--it's the only way to do what you want.
