[python-win32] Problem when I install PIL on WinXP as non-admin

[yaoyansi]

Hi all,
I installed python-2.6.5.msi on my WinXP long time ago,
Today I installed PIL-1.1.7.win32-py2.6.exe as non-admin.
Then I make a simple test:
>python
>>> import Image
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named Image

Then I logon as the admin,and run the following command
>python
>>> import Image
It is fine, there is no any complain any more.

But there must be something wrong when I install PIL as non-admin, how to deal with this problem?
