If i was getty (pre debt) i would have tried to buy dreamstime and fotolia and created an exclusive program for the group leaving contributors to choose shutterstock or the getty group.  to me anything is better than having only shutterstock growing fast and noone else except niche players.  Thats how Getty use to roll.  now they have there hands tied.
Well see what happens with adobe/fotolia and if shutterstock can maintain growth.
I would not like to see getty or Corbis keep shrinking as they are the two most likely to produce big sales.  Thats just me wishing macro and midstock a healthy life but yes we all know getty has a less than perfect history with contributors and its dominant past position.

the getty image creative search brings up like 10 million images - its never been much more than that even though they have a lot of images, video, and editorial. the actual creative search is around 10 million for me and that is up and growing.

like Michael said - the debt isn't really anything to do with Getty. It's the hedge funds that
created it to pay themselves.  I think they have to go bankrupt if they ever want to really
get aggressive and hopefully grow in new ways.  It's just to much money to make the debt payments leaving them no room to do what they traditionally are good at. Buying other companies. They have great work imo and great clients. yes its a real rough business but their debt is holding them back imo.

Im surprised Stocksy hasnt made it yet.  It sure seems like there are a fair amount of stocksy contributors here.  Getty / flickr alone has well over a million images from a small army of contributors not to mention getty house.  Maybe have two sets of results. One that only includes the ones on now and one that includes every agency and vote.
Otherwise were probably stuck with just dreamstime, pond 5 and the small group of the biggest micros.    It would be really interesting to see any data from contributors at the tiny micro's, offset!, stocksy, getty, corbis. Maybe even throw in FAA or cafe press.  Im pretty happy Leaf has shared as much as we have already. Just thinking

not a lot but i've made a little wwith the getty app

getty and corbis for sure
the aggregates that subit to them and others are great too

one way or another you need to be on getty imo for macro weather its direct or though an aggregrate

Stocksy is very transparent about it's growth and numbers to members and it is doing better and better and some people there do very well.  Everyone won't do well or be a good fit.
It sure is nice to have them setting an example making contributors part owners and paying a great percentage.  Sure they have a niche and a style. It would be really nice to
see a few more places pop up that share in profits, give you ownership, and turn a profit.
They do pretty decent for me with just a small Portfolio.  I actually feel like I should be supporting them more than I do because of what they offer as an alternative to most other agenices. Respect

So could it be 7 million exclusive photos on istock? (what they call exclusive)? ballpark? or is there just no way to tell at all. 
From what I have read so far it does help for some exclusives and not so much for others having the E+ on Getty but only a few answers so far. I was wondering how much it helped with overall sales.
Thanks

30% ballpark;) i found an interview.
