Yes, I know. Cause ShowPhoto don't have this option, I need always to open
my photos with GIMP or Krita (despite I don't need to retouch nothing in the
image) to change the print output in centimetres, changing simultaneosly the
image dpi (in attached capture you can see the Krita the powerful reescale
dialog).

Sorry, I should told "often" instead "many times". As you say, there will be
a madness to reescale photos previously reescaled.

Anyway, "Restore photography" disposable function of ShowPhoto makes a
EXCELLENT job really.
