[Image-SIG] compiling py2exe windows executable gives "IOerror image type not recognized" in the Image.open()

[francesco]

Hi,
when compiling a windows executable with python 2.3 using the py2exe 
utility my application cannot access the Image.open function in the PIL 
library because it says "IOError: cannot identify image file".

Does anybody have an idea why?

Thank you,
