Requiring source information is far more important than giving users a choice about what license to use. We should have done it a long time ago. If we want any basis in international law to claim "fair use" on images, the Berne Convention requires that we indicate the source and the name of the author.What do you think about force user to choose a licence (in a combo box) when uploading a media (pictures, sound, etc.) to Wikipedia.I second this proposal. Too many pictures just don't have _any_ information.Ditto, along with a required "source" text field.
