Isn't it considered copyright infringement to use photos of cars or illustrations of a car likeness according to iStock? I just found these under the agency collection which was uploaded in 2-2009.

I'm not picking on the person, his port is full of them and extremely good in my opinion, but just wondering why it was put in Agency if this is against their policy. Is it because they are 3d render?

Are they actual cars or did the person who did the render design it? If they did, I guess they wouldn't be infringing on any car manufacturers design.

edit: Blufish beat me to it

removed... I misunderstood

Mark designs his own car models.

He does one good job because those look so real. I only wish I had his talent.
So the way I understand it is because they are renders, then they accept them because they are generic in a sense.
