hi!

imagepath + imageurl are definately set right now, but it does not 
change anything.

	IMAGEPATH '/home/sgraeule/public_html/mapserver/tmp/'
	IMAGEURL  '/home/sgraeule/public_html/mapserver/tmp/'

you may want to take a look by yourself: 
http://igf-project.igf.uni-osnabrueck.de/~sgraeule/mapserver/tmp/

i am not sure about how to use the image-tag, so i added the following 
piece of code to the template.

<img src="[img]"> </img>

when executed umn mapserver correctly makes it <img 
src="/home/sgraeule/public_html/mapserver/tmp/WFS-Server12585768438242.png"> 
</img>
,but my firefox still does not show the picture, but just a hint that 
there should be a picture which was not found...
