JPEG image not handled.

[jnafzig]

The above image can't be added to a document despite being an apparently valid jpeg.

from docx import Document

doc = Document(None)
with open('error.jpg', 'rb') as f:
    doc.add_picture(f)

This raises docx.image.exceptions.UnrecognizedImageError. Apparently it doesn't match any existing header format listed in SIGNATURES.

This was tested on python-docx 1.1.2

Just to understand: Which device did you use to take this photo? Did you edited/converted it with some software or sent compressed via some IM chat?

The image is a plain JPG but it's missing all the Exif information inside of it.
