Microsoft thinks a jpeg bitmap is something specific

Artists maybe create jpeg bitmaps by hand?

Programmers maybe create jpeg bitmaps from text files?

Diehards even seem to be using hex editors to make jpeg bitmaps

I'm not asking about bmp file format but about bitmaps in jpeg format.
What is a bitmap jpeg file anyways?

Perhaps it would help to separate the two terms. To answer the general
question, a 'bitmap' is an image comprised of squares arranged in rows
and columns.

JPEG is a file format that contains a version of the original bitmap
image and organizes aspects of the image such as its resolution relative
to the original, file size and other factors. One original purpose of
the jpeg format was to allow journalist photographers to send images
across the internet when 300bps modems were commonplace.
