Irit Katriel  added the comment:

imghdr is deprecated as per PEP 594, so there won't be further enhancements to 
it.

[issue43194] Add JFXX as jpeg marker in imghdr module

[JiKwon Kim]

New submission from JiKwon Kim :

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.
