Thanks for that. I refuse to have a FB account so I miss out on some stuff.

Of all the links on that page, I found the DeviantArt collection most interesting:
http://www.fotolia.com/p/202869477?order=nb_downloadsI reckon that could be a competitor to Vetta or iStock's new mobilestock call but with high res work.
The collection is only 3K images and appears to be all available on subscription, so for 200 bucks you could download a quarter of that collection in highest resolution within one month. Not great for the artists but a good deal for anyone looking for some 'less-stocky'/edgy pics and a lot cheaper than mobilestock from iStock.
