I dont know if this is helpful or not but the Parade magazine that comes in the Newspapers here in the States uses a lot of stock images from various Agencies.
On the web you can look and tineye them here:
http://www.parade.com/So far I have found images from Alamy, Getty, Istock, Fotolia and SXC.hu (is SXC a free dl place?).
I have not found any of my images but maybe someone can find a tearsheet or use.
