Ahh.  Java code loading resources from a .jar file requires the leading / for 
subdirectories.  loading the image /path/to/jarfile.jar!subdirectory/foo.gif 
would fail where /path/to/jarfile.jar!/subdirectory/foo.gif would succeed.  
It never occurred to me to try it without the leading slash.  *thanks*!

Doh!  Thanks.  I hadn't thought of that scenario.

Yeah, and since you've shown me the error of my ways I can do things 
*correctly* now.  :) Thanks a million!
