New submission from JiKwon Kim <elbarkwon at gmail.com>:

Currently imghdr module only finds "JFIF" or "Exif" in specific position. However there's some jpeg images with "JFXX" marker. I had some image with this marker and imghdr.what() returned None.

Refer to:
(Section 10.1 JFIF Extension APP0 Marker Segment)
