I remember Tom Scales's pointing out, on this List, some years ago: "there is
no resolution in an image file, only pixels".
[or something like that]
Until then I had been saving files with the resolution in the filename, as if
it "knew" my intentions when saving. It was only after Tom's intervention that
understanding came and that I started to use resolution only in the printing
dialogue box.
