Yes, actually, I did mean PIL   8^s

My main problem has been the step:
- Install PIL in Windows from binaries (site mentioned above).
which the PIL binary will not do because the installer says it can not 
find a python in the win registry, (apparently the python installed with 
the zope binaries is not 'registered' with windows by zope).  The 
installer does not allow path override (nor would i know where to put it).

I can use winzip to unpack the .exe but I have no idea what goes where 
(and whether it would work)
Winzip shows 71 files, mostly .py with a few .pyd with a destination 
path of platlib/pil/  but I don't know where to extract it to.
thanks
Ian
