I read in your other thread that they must have snagged it from velospace. I'm guessing that Brooks has some ties with Velospace somehow. Uploading pics to Velospace can make the pics their property to be used as they see fit.

Just took a quick look at the Velospace site. They make no mention (that I have seen) of gaining rights to uploaded pics.
I would take 55/Rad's advice and confront Brooks about the situation. You should receive some sort of compensation and/or recognition.
P.S. 55/rad and I are both photographers so we have at least a bit of knowledge on the topic. Good luck.
