I'd be interested in seeing average portfolio size at IS for independents versus exclusives. Just a guess but I bet the exclusives in general have much larger portfolios.

You may be right in general.  In my case, though, I had pretty much exactly the same content and number of images on all sites, until I deactivated 1,000 leading up to D-Day. 

So what?  A contractor job is not a lifetime position and can be (should have been) terminated

I'll run this up the chain to see if we can make this a priority! Thanks for the great idea! I will make sure we get people on this immediately. It's comments like this that help us continue to make sure our contributors are heard!

Thank you for taking time out of your busy schedule. I know you didn't have to do us this great favor but because you have I will name my new bamboo plant after you. I hope you don't mind if I shorten it's name, as it's name tag will only allow for 5 characters due to the fact that I use bubble letters for all my name tags.

is Lobo aware that such a comment to a customer would make him fired on the spot in any other normal company ?

why nobody writes to istock's CEO ? i can't believe Getty is employing such an unprofessional employee.

They're not. He's a contractor, not an employee.

Really, though there is no way of making an accurate comparison. Some people cull their non-selling files after so long, so their RPI would be much higher than those who left everything up. (Unless they could actually remember how many they'd deleted from where).
There are so many imponderables, the most important being the actual content of ports, otherwise you're comparing apples with oranges. If apples are more popular, my port of 20 apples might outperform your port of 100 oranges.
Also there's acceptance policy.
Let's say you have a port with subjects A, B, C, D, E which sell moderately at site 1.
Site 2 however, isn't interested in subjects B, D and E, so will reject them.
Clearly that means buyers of subjects B, d and E will son lean not to bother with site 2.
Or it could be that both agencies take all, but competition in subjects A and D is much fiercer on one site.

Or ...

So IMO, comparison charts are only for fun and vague interest, and don't give any useful help to those pondering what to do with their files.
