Use a relative path do insert a graphics file (Re-post with bett er title)

[Hahn Kurt (CHA)]

I need to add a graphics file, originally placed in the same directory where
my sitemap is located.
¨There's no problem if I use an absolute path, the file is displayed. If I
use a relative path, nothing. The file is very small, so I even copied in
other subdirectories, but still nothing. How can I do that?

working:
 <fo:external-graphic
src="D:\jakarta-tomcat-4.0.1\webapps\cocoon\mount\AigleK\ecu.jpg"/>
not working:
<fo:external-graphic src="ecu.jpg"/>
