Thanks for the lesson. I understood it all.
Was PYTHONPATH supposed to be part of the Zope install?
I do a "set" from DOS and see no PYTHONPATH.
I could modify start.bat to set one I guess.
At any rate, the traceback is this
Traceback (innermost last):
File "C:\Program Files\WebSite\lib\python\OFS\Application.py", line 393,
in import_products
product=__import__(pname, global_dict, global_dict, silly)
File "C:\Program Files\WebSite\lib\python\Products\Photo\__init__.py",
line 42, in ?
import Photo
File "C:\Program Files\WebSite\lib\python\Products\Photo\Photo.py", line
56, in ?
import PIL
ImportError: No module named PIL
Thanks for all this effort
Dale
