This site is taking free images and redistributing them for money. Although RGBstock has images available on other sites, it would be wise to see if they have any of yours. They definitely are offering matchstick's Lime splash.
I was contacted on another site by the webmaster - emid123 - and told he was using the image there. Clearly he has no idea of the rules. I just hope if he's here he reads the terms and sticks to them. I told him to remove my image. He claims he did, but unless you pay him money, you can't see what he's stealing. He says the first 20 days are free. They are - IF you pay up front. Otherwise you have no access.
Please refer to the following thread.
This person is a spammer. He says he doesn't use other people's images, and yet he posts under their images that he has used them, and places a link back to his site. Pure spam.
@2 The thread you refer to further implicates you and brings suspicion about your "marketing" intentions.
You should seriously consider what your intentions and plans are here before you proceed with anymore marketing efforts.
