But note the "approximate" in there. That means you can end up with a file 
that is larger, and some systems reject files that are too large. And there is 
a point where lowering the quality settings really degrade the image.

And I've seen files which were up to twice as big as others with the same 
quality settings (and for the same image size in pixels)...
