Can low temperatures damage a bike?

you are right about the first part - the photo is taken by somebody working in a bike shop and thee are some horrors.

I am not so sure that the whole frame needs to be full of water. I am guessing that once the top surface of the water has frozen - like on a lake - it acts as a plug, so the water cannot go updwards, just sidesways as it expands.

In that situation I wouldn't expect the top to freeze at a quicker rate in comparison to the rest of the water due to the lack of airflow over it, if the rest of the water was protected, and you had the top exposed to airflow (pretty much like a lake) then yes, the top would freeze first.

It seems that way to me, also. I see a bit of this in frames I work on, now and again, never to that extent, though.

In very cold weather, I've had gear shifters and jockey wheels freeze up.

The only issue you may have is cables, freehubs and mechs sticking because they are frozen. Otherwise, don't worry.

Can a vented tumbledryer without a vent which causes moisture in the garage damage a bike..?

It will certainly rust any exposed metal ( chain rings, cassette, chaine, bolts ) due to humidity caused by the warm air coming out of the dryer.

A side-effect of cold temperatures is that salty grit is likely to have been used on the roads and that most definitely can damage bikes by acting as a grinding paste on the transmission, or by promoting corrosion!
