doh, you are right.  It saves it in the directory specified in the  
chameleon.xml file.  This is generally the same as you would use in  
the WEB object of your map file.

You should be able to find the directory of the scalebar image in  
this session variable:

$_SESSION["gszTmpImgPath"]

The actual name is not saved in the session, you would need to modify  
the scalebar widget to store the generated name in the session.

Cheers

Paul
