Having been a stock photographer for some time now I can't help but watch stock agencies growing so large its insane. There are so many photos available I believe that its time to start weeding them out. Having been a graphic designer for several years I know that looking through millions of photos is not going to happen. Like searching on Google for anything most people will not go past the first few pages if past page one at all! On these large stock sites I believe its similar, how many pages back does a customer search?
As a result of these large stock sites I have created the smallest free stock photo site in the world with just one photo that changes daily. its called unostockphoto.com and is a fun way to go in the opposite direction from these mega sites.
