OK, I'll try to be clearer.  _The same_ script does the image and the 
map.  If images were inlined in HTML, I'd write something like

<div tal:define="img_and_map here/generateImageAndMap">
   <img tal:content="img_and_map/img" usemap="#mymap"/>
   <map name="mymap" tal:replace="structure img_and_map/map"></map>
</div>
