Judi,
I would compare the contents of your jar files - the one that works vs. the
one that now doesn't work. i.e. jar tf workginJarFile.jar > l1; jar tf
nonWorkingJarFile.jar > l2; diff l1 l2. This might help you see if, for
whatever reason, the images didn't make it into your current jar file.
Good luck.
