As some of you may have seen in the Photo of the Day thread, I recently posted some photos I took at a car show. The owner of one of these cars contacted me this morning on another forum where I also posted said car and asked for permission to use my photos on his website (dedicated to this particular car, a Ford GT40 replica). I have no problem with that of course, since I don't do this for a living, but wanted to seek out the advice of those of you who've been in this position. Any particular thing I should be wary of? Is my simply emailing this guy back and giving my permission sufficient? Are there any strings attached (for example, can I ask that it not be used for any commercial gain?). Just curious.
