Not sure on the copyright bit but a word on advance planning if you intend to charge and then donate the proceeds to charity such as RAFBF. Snag is if the cash goes through your account those nice chaps at the Inland Revenue say it is income and tax you. The fact that you pass on the same amount to charity is your own affair. How do I know this trivia? Well once worked for a very high priced individual who submitted an article to the professional press and was, surprisingly, paid. Passed the cash to Army Ben Fund but because the publishers had declared the payment as an expense to themselves the tax man promptly asked for his cut from my boss. Guess who was tasked to sort it out ... and who actually wrote the article in the first place
