Usually there are responses which are not compressible, so trying
to gzip them is just a waste of resources. Also there can be
cases when the client announces gzip support, but in fact have
problems when some types of responses are compressed - for
example, there were problems with compressed javascripts in some
browsers in the past.

If you are sure that in a particular configuration all possible
responses must be gzipped, "gzip_types *;" should be fine. You
may want to limit it to a particular location or server though.

As long as Content-Type of the response is "image/jpeg", there
should be not difference between "gzip_types *" and "gzip_types
image/jpeg ...". If you see a difference, please provide more
details - full configuration and a debug log would be ideal.
