Story 2121: Stock Photo Business Gets Smaller Published: 9/8/2009   It is time to revise previous estimates of industry revenues based on what has happened in the past year. For several years, we have estimated the size of the worldwide market for still images and illustrations at about $1.8 billion. We have also maintained that overall, this is a no-growth industry, despite the fact that some companies and individuals could point to growth. For 2009, expect gross sales to decline to, at best, $1.45 billion, dipping about 20% below 2008.
