Ohh, but Fax machines interpreting JPEG are actually very rare. Yes, it's in the standard, but so far I've only seen a Samsung one actually doing it.
BTW you can find out if your fax has such features by looking at the capabilities it announces diring the negotiation phase. Most laser fax machines have some "T30-Trace" feature to print out a commented debug trace of your session.
