[Zope] PIL/Zope Problem

[Marcello Lupo]

Hi to all,
i read all the documentation and made all things to let interact PIL and
Zope and i cannot find the way to make it work.
If i try to import PIL from pyton interpreter it works perfectly with:

*******************************
Python 1.5.2 (#1, Jul 17 1999, 22:10:16)  [GCC egcs-2.91.66
19990314/Linux (egcs- on linux2

>>> import PIL
>>> data=PIL.Image.open("/home/httpd/listanozze/docs/images/prove/ccc.jpg","r")
>>> print data.format
JPEG
>>> print data.info
{'adobe_transform': 1, 'progression': 1, 'adobe': 100, 'jfif': 258}
>>> print data.size
(450, 309)
>>>                          
******************************

as you can see it works.
But when i try to access PIL.Image.open from an external method in Zope
i get:

                data=data.resize((128, 128))
