I agree, but the MOBI rendering software chokes if it is not present. As you wrote before it’s a bug, but I just wanted to document what triggers it.

I did some testing and found that kindlegen fixes this by adding JFIF metadata to JPEGs if it is not present in the source file, so that books published on Amazon do not exhibit this problem.
