Comment (by Alex Morega):
FWIW, the call to `Image.new(...).save(...)` looks distracting to me, and
makes the example hard to read. PIL can read the 35-byte GIF from this
StackOverflow answer: https://stackoverflow.com/a/15960901. I think it
works better as an example because it's just a blob of binary.
{{{#!python
>>> from io import BytesIO
>>> from PIL import Image
>>> img = BytesIO(
... b'GIF89a\x01\x00\x01\x00\x00\x00\x00!\xf9\x04\x01\x00\x00\x00'
... b'\x00,\x00\x00\x00\x00\x01\x00\x01\x00\x00\x02\x01\x00\x00'
... )
>>> img.name = 'myimage.gif'
>>> pil_image = Image.open(img)
>>> pil_image
<PIL.GifImagePlugin.GifImageFile image mode=L size=1x1 at 0xFFFF9392BF40>
>>> pil_image.verify()
}}}
