I've actually been on the site for 2-3 months and here's my experience. You start out with low paying (usually 4 images for $50 but one assignment wanted 10 images for $50) assignments and as you establish a successful track record the assignments pay better as you progress. That's the pitch, but in my experience they're very picky about accepting images, to the point of my not being able to making sense of what they do and do not pass on to the client. They offer no feedback, so there's no real way to learn as you go along. The pay is extremely low at face value, but even lower when you account for the fact that many of their assignments require multiple models and locations when the payout is only $50 IF they buy four images. Deadlines range from 3 days to two weeks. So far I've responded to two assignments and sold 1 image. It's a great idea, but it's being implemented rather stupidly.
