All I did was run http://jempeg.sourceforge.net/InstData/MacOS/NoVM/install.bin and it all worked first time.Yup, that'll work too; but it'll install an old version of the jempeg software (0.9.13). You can plug the new version into there, by grabbing the jempeg-0.9.14.jar from SourceForge, removing jempeg-0.9.13.jar from the lib directory where it's installed, renaming jempeg-0.9.14.jar to jempeg-0.9.13.jar, and dropping it where the old jempeg-0.9.13.jar was. But then you don't get the benefit of having Swing around for any other Java apps you happen to want to run in the future. :)
