Earn money with your photos. With GStock Photo Microstock Management Software you can tag all your images easily, and upload them to the most popular microstock agencies. Microstock photography (or micropayment photography) is a part of the stock photography industry. Microstock agencies source their images almost exclusively via the Internet, and sell their images at low rate compared to traditional stock agencies.
