that doesn't work if the file doesn't exist.

a more robust solution (which doesn't require any changes to
the library) is to open the file at the application level:

    try:
        file = open(filename, "rb")
    except IOError:
        # the file doesn't appear to exist
        ...
    else:
        try:
            im = Image.open(file)
        except IOError:
            # not an image file; get rid of it
            file.close()
            os.remove(filename)
