Would an elecrical oscillator such as the small ones shown in this
picture mind which way round they are installed?

If it's a quartz crystal, no.
If it's a whole circuit to make an oscillator, yes of course, it will
have a +ve and -ve, and generally an output too.
that photo is not of 'oscillators' of course. It's of crystals. They are
*part* of an oscillator.
2 terminal oscillators are certainly possible. But they're just crystals.
I've never seen a crystal oscillate on its own.
FWLIW I expect they do, moving back and forth due to environmental vibration. With high Q they can't build up much movement, but it's not zero.
