[Pythonmac-SIG] I can't grok PIL anymore...

[Jerry LeVan]

Here is an even simpler demo of my problem...
mandrill.jpg is in the directory where
python is invoked.

[macjerry:~/python]$ pythonw
Python 2.4.1 (#2, Mar 31 2005, 00:05:10)
[GCC 3.3 20030304 (Apple Computer, Inc. build 1666)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
 >>> import Image
 >>> im=Image.open("mandrill.jpg")
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File "/Users/jerry/Library/Python/2.4/site-packages/PIL/Image.py",  
line 1745, in open
     raise IOError("cannot identify image file")
IOError: cannot identify image file
