Splendid. Thanks.

I am learning new thing with every new email, yes. Thank you for the  
reference to your book.

It looks increasingly like I have to dive in to the workings of the  
geoserver to be able to output png files of a mashup between my  
geotagged images and my maps.

Having participated once in a OpenStreetMap mapping session, I wonder  
if OSM is run on top of GeoServer and could be used together with i.e.  
OpenLayer to do what I want? Still - downloading and installing  
everything needed, seems laborious compared to a simple conversion  
from shapefile to png.

Any particular reason why a simple conversion between shapefile and  
png seems so cumbersome to do via a simple program accessible through  
the command-line?

Hm... Not sure I am out of the woods yet, as a png seems a long way off.
