As someone who had his image ripped off and found as a half page spread in the Sun, one understands the problems, luckily the site involved pursued it and we eventually settled and split the fee we were paid… Grrrrrrr.
I had one of my pics ‘doctored’ and printed on the front page of the Daily Telegraph. Sent a huge invoice to them with a copy of the original photo, claiming breach of copyright and they settled it with a letter of apology. At the end of the day, if you don’t see your pic published, they will get away with it!
