Reproducing old photographs from vintage books, to share on the Forum?
Does anyone know where we stand with regards to reproducing photographs from old books that date to WW2 or the late 1940s, please? If it's an old book and there is no information inside prohibiting the reproduction of photographs, diagrams etc, is it acceptable to do so? I have a number of vintage books which are to do with both WW1 and WW2 which have interesting photographs in and I believe that fellow Forum members may find interesting. Obviously reproducing the photographs wouldn't be a venture to make money but simply to share the images with fellow forum members, here on-line, for military history interests.
Do published photographs have indefinite copyright protection even if no mention is made within the publication prohibiting reproduction? Or are published photographs only copyright protected for a set number of years, after which they can be reproduced? I would guess that most of the photographs involved were taken either by official crown/service photographers or press photographers.
Thanks for any information.
