The photographer in question (a proudly self-described amateur) is very happy with the fact that his photo was used. He chooses to publish his images under a Creative Commons attribution license because he wants people to freely reuse his work (providing they give attribution) and he doesn't want the hassle of personally responding to scores of individual use requests. And even when he learned that the photo in question was going to be used in Iron Man, he declined financial compensation, believing that having his image used in such a cool context was reward enough.

Here is a comment Mr. Keith made in the Flickr comments for his photo:

“Thank you, DSK Saways. I think you summed it up nicely: “The money aspect of it simply pales in comparison to the fact that [my] photo is backing Jeff Bridges in a movie.”"
