user_comment gives error #15

Closed ahmetceltik closed 5 years ago

ahmetceltik commented 5 years ago 
with open("images/samples/img12.jpg", "rb") as file:
            img = Image(file)
            print(img.user_comment)

Gives a nasty error:

I just released version 0.5.1 of the package (see #17) which adds support for parsing the user comment data structure. Don't hesitate to follow-up with an additional issue if necessary.
