Well, the code is cut and pasted from the Zope Book, so I am
_assuming_ there are no errors in the script. And, like I 
said it works fine on other images.

What I am trying to determine is if there are any
limits set on External Methods which I might be running in
to trying to process such a large image. I have looked
through many pages of docs and everything seems to be
saying that External Methods are unrestricted.

Is that true?
