Found some information at the following site:

The author is posting his experiences as a microstock photographer. There's about a years worth of detailed financial information listed. Over that time, his income has risen about 42 percent, from an average of $476 to an average of $677 per month (those are 3 month moving average numbers, to even out the fluctuations). Over the same period of time, his image portfolio has risen about 54 percent in size, from 2624 images to 4054 images now (again, 3 month moving averages). The average earnings per image is about 17 cents per month.
To achieve these numbers, he's listed with between 8 and 10 agencies. Istockphoto, shutterstock, dreamstime and fotolia account for the majority of his income.
So once again, we find an income in the mid to upper 3 figures per month. Over the last year he's grown his portfolio by roughly 1400 images, or roughly 4 finished images per day, working 7 days a week. That seems like a fairly high level of dedication to me.
I must admit, I feel a bit discouraged. I see photogs like the guy above working their butts off to average less income per month than your average hamburger flipper; then I go to shutterstock, look in the critique forums, and see rejected work that I think is actually awfully good.
As near as I can tell, if you're amazingly talented AND work like a madman on Crack, you can earn about 20% of a decent income. Or less.
Am I reading this business wrong?
