Also it may be helpful if you are able to tell us which version of JEuclid you 
are using.

Hi Paul,
The NullPointerException is coming from the ImageInputStream being null. This looks like one for Max as I suspect it may be a problem with the JEuclid PreloaderMathML class when it constructs its ImageInputStreamAdapter. Could you host your source document somewhere and I'll take a look at it.
