Sell RF/microstock images, no. (Places like shutterstock, Istock)
Sell RM images, yes. (Places like alamy (free to setup, 60% sale goes to you), photoshelter (expensive to setup yearly, 90% sale goes to you))
You are better off to try to get on a real stock site with potential for real payout instead of pennies.
give a place like Alamy (based out of the UK) a try
http://www.alamy.com/
They do either RM (Rights Managed) or RF(Royalty Free) sales, your choice.
And 60% of sale goes to you, unlike the microstock sites where you might get 20% or less of the 1$ they sold it for.
RM pays much better, RF is a commodity market, based on high volume low value product.
In either case they all want signed model/property releases for any people or private property appearing in your shots.
