G'day,

> Q: Do you know which .jpg files were saved as progressive?

I think all in org/openscience/jmol/images/*.jpg were. It wasn't clear which of them was actually crashing the JVM (not just an exception but a full-blown crash), so I saved all of these JPGs with progressive disabled, repackaged, signed the JAR and the crash was avoided.

Two reasons:

1. to avoid the bug mentioned above in older JREs (someone might add new JPGs to the JAR that trigger this bug - we should be using PNGs actually)

2. for those who want a smaller (marginally faster to load) application JAR

Not essential, but nice to have the option.

Regards,
Chris.
