Colorful Illustrations 93°C

I've just been told by Darren Di Lieto (of Little chimp Society and Hire an Illustrator) illustrators (including myself) have had their work pinched and then published in a book, along with the interview I did with LCS a while back.
Most of the work seems to have been pinched from my own website, which i guess could serve me right for putting big-ish images on it, but more annoying i now have to work out whether to try to combat this with some clever web tech. or use dreaded watermarks.... something I have aways been against.
Still not sure what to do about it (the flattery of being included amongst other greats has warn off) but felt the need to warn folks not to buy it. As Darren mentioned "Someone has made a lot of money from this book and it wasn’t me or the unknowing contributors. So please do not buy it!"
