[Zope] External Method: Render STX with images

Hi,

people who wanted to have images in their stx documents. I've just uploaded
a python solution you can use as a simple way to provide this feature:

this doesn't somehow work properly on my system.
i am using zope 2.4.1 ( stable version ) and i hacked the
DocumentWithImages.py file as you descibed some topics before.

when i use a sting that shoulb be converted into structured text everything
goes fine, but when i try to hand over a document to your method the
following attribute error occurs:

Error Type: AttributeError
Error Value: expandtabs
