NCL Cruise Lines saw one of my images and asked if they could post it to their social media sites and gave me a link to their terms. Sounds like a sweet deal. They get full, unfettered rights and as far as I can tell, I don't even get credit.

"I hereby grant to NCL Corporation Ltd., it subsidiaries, agents and affiliates, the unlimited worldwide, perpetual, unending right to use, reproduce, distribute, and convey my image/photograph in any format or medium now known or subsequently developed, to modify and edit my image/photograph, to combine my image/photograph with other images, video, audio, text and other media, to create derivative works incorporating, including or based on my image/photograph, and to sublicense any or all of the foregoing rights. This grant shall be construed broadly."
