Playing audio over bluetooth also wakes things periodically, but it uses almost no power. With a similarly competent design photo transfer should be very battery efficient.

No, most(if not all) bluetooth controller has audio offload, basically the cpu does not involve(or very little) when transfering data from storage to radio.
