Shutterstock, the world’s largest subscription-based stock photo agency, announced that it has acquired BigStockPhoto, a leading credit-based stock photo agency, headquartered in Davis, California. Financial terms of the deal were not disclosed.

“BigStockPhoto is a leader in the stock photo industry, and an excellent fit for Shutterstock as we expand into the credit-based market,” said Jon Oringer, founder and CEO of Shutterstock. “This addition will enable Shutterstock to better satisfy the diverse payment preferences of stock photo buyers worldwide.”

According to the deal, BigStockPhoto will remain a separate entity, and Shutterstock plans to grow the company’s global presence by investing heavily in marketing, infrastructure and user experience.

BigStockPhoto was founded in 2004 to provide an alternative to high-priced stock photography, and to create a marketplace for photographers to sell their work. In addition to its diverse library of 3.7 Million royalty-free photos and vectors, the agency has created a vibrant community of image buyers and submitters from around the world.
