We're excited to announce that Shutterstock is sponsoring 'Photo Hack Day,' this weekend, August 20 and 21, at General Assembly in New York City. The event is all about building cool new tools for photographers, artists and consumers who love pictures. We'll be joined by several image-centric technology companies, including Instagram, Tumblr, Etsy, yfrog, and Face.com, and it's already garnering lots of media attention (see TechCrunch article). Much like the recent Shutterstock Hackathon, this event encourages developers to build creative new apps during a 24-hour period. The winners will collect cool prizes and have their work displayed on the massive NASDAQ screen in Times Square. If you're in the New York City area and are interested in participating, visit Photo Hack Day's website. We'll also be tweeting live from the event, and recapping the highlights here on the blog.
