PIL is a (semi-standard) Python module, so its all pure Python...

1) Windows or Unix?

  In Windows, the standard way seems to be to have Zope use a new
  Python install in c:\Program Files\WebSite\bin, unless you changed
  the defaults. In Unix, the standard seems to be BYOP (Bring Your Own
  Python).

  The diff is that to get things working under Zope for Windows, you
  need to install it in zope's python, *not* the 'normal' python install
  that you may or may not have (c:\ptython15 or c:\python20 or such)

  Win: put it in $ZOPE/bin/lib
  Unix: install it in your regular ol' pythonpath (/usr/local/lib/python,
    or whatever)

2) Need to add to path?

  You may have to set the PYTHONPATH arg to find it. PP is an
  environmental variable that lists places where libraries could be.
  If the above doesn't work, try changing your Zope start script to:

  Windows:
  SET PYTHONPATH=<whatever_it_was_before_if_anything>;C:\zope\bin\lib\PIL

  Unix:
  export PYTHONPATH=<whatever>:/usr/local/lib/python/PIL

  (the Unix is bash syntax, if you're a csh user, you probably know
  to change the 'export')

  [ I didn't have to change my path, YMMV ]

Try it out:

  c:\Zope\bin\ > python
  
  Python 1.5.2: import PIL


BTW, ExtImage is a great app for wrapping images to handle properties,
cataloging, auto-thumbnails, etc. Some features (thumbnails, etc) require
PIL, which a great reason to install it.

HTH,
