In a nutshell Rachael Hale is a series of pictures of Dogs in Hats! Simple concept, but they seem to have made plenty of money out of it! My idea is to build up a database of royalty free pictures of dogs in hats with the view of knocking out a book in the golden 100 days before Christmas. One quick question for any readers - if a person posts a picture of their dog on facebook and makes it public, is that picture then freely in the public domain?
