Motivation and context
It doesn't make much sense to encode the image as JPEG if the given file name is "image.png". Instead, let PIL select the format based on the requested file name.
This was originally a part of #6483, but it's not directly related to the topic of that PR, so I decided to submit it separately.
How has this been tested?
Unit tests.
