Why not?

Yes, you can write an http request handler that can return an image as a
string
(a raw binary string, that is).  Actually, it would probably be simpler to
just
make the handler save the image as a file in a temp directory and return it
as
a file.

Not really, you need to learn medusa first.  Actually you should learn
python
first, then medusa.  This probably shouldn't be your very first project. :-)

Makes sense to me.
