Yes John - very well spotted Funnily enough, this is related, its because they were using stock, that I approached Yellow with the suggestion that they commission their own photographer. Best cold call I ever made, as I got an amazing commission to do most of the Yellow Pages "Get About Guides" in the front of all their directories. This removed their issue of all their expensive admin work, and costs paid toto all of the different stock libraries they had been using.
Funnily enough, it was because of that work with Yellow Pages, that gave me the idea for my business name of Longshots
Good to hear that some people have made something out of stock. I'll admit to being cynical after being ripped off by the agency that sold my work, but never passed on the income.
