Workaround for me to pic size with Opera browser is to just move slider that I normally use to make print smaller. That immediately shrinks the pics, too. Other browsers likely work the same.
JRB are different, "orthogonal" --not contrary--, in the direction of their UQ baffles. Do you recall their explanation, sometime in yesteryear, of why they have found it works as well, or even has advantages, in their view?
