Here is an article written by a lawyer about copyrights. https://www.socialmediaexaminer.com/copyright-fair-use-and-how-it-works-for-online-images/ . Basically
it says any picture that is taken, any thing that is written and any thing that is drawn or is painted is copyrighted the instant it is created. It does not have to be registered to be copyrighted. So with some exceptions anytime you cut and paste on the internet there is a good chance you are breaking copyright laws.
