As you're using normal write() calls to sys.stdout you'll be messing up 
your \r and \n bytes in the image: sys.stdout is a text-mode file so 
you can't write binary data to it. At least: not on Windows. You'll 
have to somehow reopen the file in binary mode, but whether the unix 
idiom of
fp = os.fdopen(sys.stdout.fileno(), 'wb')
works on Windows remains to be seen...
