Well there is nothing much you can do lah, except to get him to take it off loh. Looking at it, he probably have put it up there for God knows how long. Likely, anyone who visited his site is likely to be under the impress that the photo is taken by him. That is very disappointing because the bare minimum one can do is to credit the author, since he himself is so call "from the industry", and supposingly an "accomplished photographer" who constantly encourages juniors to shoot more and engage more, and actively monitor various porn sites across the internet including the infamous Sammyboyforum for leeching the photos of models.
He has allegedly intentionally scaled down the words so that even if we enlarge it in photoshop - normally and for most people they can't tell or make out what the words are. Unfortunately, some people can, and they eventually will.
From his profile in friendster, and based on the theme of the picture he has stolen it to impress those are like those kind of pictures and probably of the faith.
Of course, there is a possibility that he might not reply to this post and tomorrow he might just post another ad to rent his equipment, which I strongly suggest should be boycotted as well, as we do not know what values such a person might bring to those juniors they come into contact with.
