What's your understanding of "fair use" of a copyrighted picture? For example, those occasional "Caption This" threads which take a picture off a web site (CNN, ABC, etc.) and invite people to write funny captions for it. As often as not, the content is political, and that's where I think the ambiguity may begin. Using political images is not, from what I understand, copyright infringement if it is used in a parody context. For instance, if I take the GOP elephant and use it along with a funny phrase, or alter the image slightly to make it satirical, that's not considered copyright (or trademark) infringement. But if the subject is a picture of, say, Howard Dean, taken off CNN's web site, and you're parodying the subject, is that considered fair use? You could make an argument that the subject is political but the picture is not. That's where the confusion comes in for me. I've never heard of any website that's used photos in such a parody context being sued or threatened, but then again, it's a big net. Anyone got any experience/insight into this?
