The moment that photograph becomes digital, it's worthless. Equipment, travel, time, none of that matters when the end result is an arbitrary configuration of bits which can be copied perfectly, ad infinitum. This truth applies to anything in a digital format. All of the books, movies, games, documents, video clips, photographs - all of it is worthless, and no one
deserves compensation for any of it, regardless of the effort that went into making it.
The photographer would need to be be compensated for their time and effort beforehand, if at all, but the age when one can expect to be paid for content or knowledge seems to be rapidly coming to an end. "Freebooting" is only a problem because we've tried to make ownership and copyright work in a medium that renders them irrelevant, but really it's just the web working as intended.
Like a lot of people here, I benefit personally from being able to assert ownership over digital content, but I can also see the writing on the wall.
