This is my stock photography sales statistic for March 2010. You can find a complete list of stock photography agencies that I work with here.
These are for me the best 4 performing stock agencies for March 2010:
March was an OK to good month, but with an decrease of 22% compared to February . It was the best month ever for iStockPhoto, YAYmicro, GraphicLeftovers and Zoonar. DepositPhotos is still my best earner and there is an increase in sale, but more then 90% of the income with DepositPhotos is through the referral and affiliate program.
