Then that is specific to Org, and is not really relevant to the issue
we are discussing here.  If Org cannot give a way to select the format
in which the image is stored, then we'd need to consider this speciall
for Org.  (And still, I don't really understand why you care about the
format Org uses to store an inline image.)

JPEG compresses better, but it also loses information.  So I think
even in this situation, PNG is a better choice I fail to understand
how the small increase in disk space could be such a serious issue
nowadays.

With my suggestion, you can still select JPEG, even if the default is
PNG.
