I always make a point of checking the 'File Info' as tge last thing I do in PS before saving and/or posting. I want to make sure that all my copyright metadata etc is embedded. So imagine my surprise when I read via the BFP April Newsletter that a number of Social Media site routinely strip copyright date when they post our pics. Those mentioned include FaceBook, Twitter and Flickr! See here: http://www.embeddedm.
I would be interested in your thoughts.
