> import os, sys
> import Tkinter
> import Image

> for infile in sys.argv[1:]:
> 	outfile=os.path.splitext(infile)[0]+".jpg"
> 	im=Image.open(infile)
> 	# print infile,im.format,"%dx%d" % im.size,im.mode
> 	im.save(outfile,"JPEG")
> 
>  However on running this I got the following raise IOError
> 
> C:\Program Files\Python\Scripts>python myconvert_jpeg.py image12194.tif
> Traceback (innermost last):
>   File "myconvert_jpeg.py", line 17, in ?
>     im.save(outfile,"JPEG")
>   File "C:\PROGRAM FILES\PYTHON\PIL\Image.py", line 666, in save
>     SAVE[string.upper(format)](self, fp, filename)
>   File "C:\PROGRAM FILES\PYTHON\PIL\JpegImagePlugin.py", line 298, in _save
>     raise IOError, "cannot write mode %s as JPEG" % im.mode
> IOError: cannot write mode P as JPEG
