Worse from month to month and I stopped uploading a few weeks ago.
With a portfolio of over 2000 images, I sold a single photo this month!
Not good!

No good for me. Dropped from around 5% to 1% of my earnings this last six months. I still upload 30-50 images once a month, but probably won't bother in 2011

They're doing okay, not great but just okay for me.  Down 17% from 2009 to 2010, which isn't as bad as Dreamstime at -26%.  BigStock is 4.9% of my total for the year, which puts them in 7th behind SS, iS, Ftl, 123, Veer (thanks to the D4¢) & DT.
