(This is a follow-up to Debian bug report #255720 - please see
http://bugs.debian.org/255720 for details.)

I've just realized that this bug report has not been forwarded to
rrd-developers but the original author of the Python bindings. However,
there has been no reply since then.

I think this feature (i.e. getting the image into 'file' instead of on
stdout) would make sense. However, I'm not into Python at all, so I hope
that someone else steps up to implement that (or convince me that this
feature does not make any sense ;-)).
