    The following are outputs are from my routine myconvert_jpeg.py--- listed below. 
   The first output is when I activate(deactivate the im.save line) the print line to establish that the file has been recognised and its format detail. This works!
C:\>python c:\progra~1\python\Scripts\myconvert_jpeg.py c:\progra~1\python\Scripts\image12194.tif
c:\progra~1\python\Scripts\image12194.tif TIFF 853x603 P

# myconvert_jpeg.py
# The Python Imaging Library.
# developed by Frerik Lundh
# convert image files
# to JPEG files
# usage is myconvert_jpeg.py imagefile.* 
# creates imagefile.jpg-----hopefully

import os, sys
import Image

for infile in sys.argv[1:]:
	# print infile,im.format,"%dx%d" % im.size,im.mode

    The second output is the result of when I try to save the tif file as a jpeg file.

C:\>python c:\progra~1\python\Scripts\myconvert_jpeg.py c:\progra~1\python\Scripts\image12194.tif
Traceback (innermost last):
  File "c:\progra~1\python\Scripts\myconvert_jpeg.py", line 19, in ?
  File "C:\PROGRAM FILES\PYTHON\PIL\Image.py", line 655, in save
  File "C:\PROGRAM FILES\PYTHON\PIL\ImageFile.py", line 125, in load
  File "C:\PROGRAM FILES\PYTHON\PIL\ImageFile.py", line 175, in load_prepare
    self.im = Image.core.new(self.mode, self.size)
  File "C:\PROGRAM FILES\PYTHON\PIL\Image.py", line 40, in __getattr__
    raise ImportError, "The _imaging C module is not installed"
ImportError: The _imaging C module is not installed

Can anybody tell me what is wrong? I have run the viewer.py script(comes with PIL) with this file and it works!
Incidentally this last message is the same as when you run pilconvert.py(comes with PIL)
