http://www.polyvore.com/cgi/aboutI'd never heard of this site before today, but my google alert (looking for images in use) found these:
http://www.polyvore.com/cgi/thing?id=1272314The image shown is a watermarked comp from StockXpert, but if you look at the pages that use the image in the collage/montage (not really sure what it is), on the right are some links to the places to get the items put together, and there is a link back to the image page at StockXpert where someone could buy the image if they wanted.
My first reaction was that this is almost like a referral site - these collages are essentially ads - rather than someone improperly using a watermarked comp as a finished part of a website. I can't imagine how this site is going to generate many sales - who buys clothes with a bag, shoes and a stock photo?
If you go to the interface to create a page, they have a tab for "backgrounds" and the only site that sells images (there are a bunch of freebie sites) is StockXpert, so I assume this is a partnership deal that StockXpert explicitly set up? Did I miss an announcement on this?
