This is from one of the leading copyright attorneys in California in response to a query from me.
"Generally, if you registered before this infringement (or if they infringed first but you registered within 90 days of your publication), then you have access to a range of statutory remedies, which cases we take on contingency regularly as a result. If not, then you have an actual damages case, which given your deal with Getty means there is an established royalty rate, which will be less than the scope of what is available in statutory damages (up to $150k if willful and here you have facts that evidence willfulness; and attorneys fees). Their fair use defense is not great given the commercial nature of the magazine and web-page, but they will certainly assert it. Here, they have infringed your exclusive rights by reproducing it, publicly displaying it, and also creative a derivative work/adaptation of your work. Let me know your status vis-a-vis registration and we'd be interested in exploring this further with you."
