As you can imagine, I have neither the sort of time or money that I would have to devote to a legal action.

As a matter of fact, I think that this is becoming a real problem : some people obviously decided to treat us like some sort of free-of-charge, don't-say-thanks, step-on-our-licences source of images, precisely because they know that, in practice, nobody will  seriously complain.
(Which is quite ironic on the part of people who are easily offended by "piracy", when it's about a 15-year copying mp3s of lousy albums he'd never buy anyway.)

Of course I'd like to see one patent example of such violation taken in court and serve as an example for others, but this means that someone will have to actually take the burden on his shoulders (and personally, that's not my career plan).
