Review comment (suggestion):
`image` should be a `PIL.Image.Image`, because `PixelArray` is a NumPy array and those don't have a `save` method (there is a `numpy.save()` function, but it's used differently). Around the source code, the argument which is passed to this method is effectively a `PIL.Image Image`.
