Of course the initial compression causes some minor loss as well.

It has been my understanding that if you only open a jpeg for viewing
and close it again, there will be NO degradation to the original
image.
That it's only manipulating a jpeg image and *then* saving it that
creates small losses which accumulate and soon become noticeable.
IOW, don't manipulate a jpeg and you won't suffer image degradation.
True or not true?
True. Opening a jpeg file for viewing then closing it doesn't change
the file.
Opening a jpeg file then saving it when closing can change the file,
since it is then being recompressed.
