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.
