This may be a daft question...(i know it is).
We all know the copyright laws when posting images etc , making sure we get permission before posting. What about posting old photographs or old drawings?..ones that come from libraries, or old books, papers etc..At what point does the copyright law change, if the subject of your posting is that old, the person who owns the copyright may no longer be with us. Does this affect what you can and can't post?
