I didn't say 'all of them'.
BTW, can someone tell me how to GIS from Flickr images which are right-click protected. Someone put me onto a program, but it only worked once then failed.
If you search Flickr for Shutterstock, Dreamstime, Fotolia (hehe), etc you get lots of hits, but how many of them are stolen from SS and how many the tog is indicating are available from a site (probably against Flickr's T&C) it's hard to know.
