Bill Graham Archives vs. Dorling Kindersley Ltd., 448 F.3d 605 (2nd Cir. 2006): Reproducing Grateful Dead posters within a book was ruled Fair Use by the 2nd circuit court, primarily because of the size reduction and use in a timeline. In US copyright law, there are four factors that are considered when determining Fair Use, including purpose of the reproduction (which includes whether the reproduction is of a commercial nature) and the size of the reproduction. I find it hard to see an argument where a forum avatar isn't Fair Use. (Although it is worth noting, Gold, that things can be both trademarked and copyrighted, and many logos are.) On the other hand, widespread distribution of materials, especially without means of policing the distribution, is extremely easy to use for breaking copyright laws. As such, it is in the Orr Group's interest to not implement such a feature. If you've got stuff you want to share legally, there are plenty of other ways to do it. Hell, if you've got an entire campaign full of stuff that you have the rights to distribute (and you must of or have permission for all of it), you could submit the campaign to the marketplace and make money off of sharing it. =) (My father listens to an all-Dead-all-the-time satellite radio channel. It's got studio recordings, concert recordings, and covers of Dead songs, plus stuff by Furthur, The Other Ones/The Dead, Rhythm Devils, and solo stuff from people that were at some point members of the Grateful Dead. Despite being "older than dirt" in his own words, he would still attend Furthur concerts, at least one a year if not more.)
