 """ Indicate whether the specified image file is valid or not. @param file_path_name: absolute path and file name of an image. @return: ``True`` if the image file is valid, ``False`` if the file is truncated or does not correspond to a supported image. """

    # the CRC checksum in the image.  The only way to check from within
    # Pillow is to load the image in a try/except and check the error.  If
    # as much info as possible is from the image is needed,
    # ``ImageFile.LOAD_TRUNCATED_IMAGES=True`` needs to bet set and it
    # will attempt to parse as much as possible.
