That sounds much more reasonable. One problem is that I don't really want to having something like 'crossfire is distributed under the GPL except for these 5 images'. This could also prove problematic for him - the fact that many files say the crossfire is distributed under the GPL - someone could easily grab it, think that the image is in fact under GPL (and in fact, there may be nothing that actually says it is not). Ironically enough, if crossfire was in fact closed source, various restrictions would be more agreeable to me simply because the control of the files is higher - easier to know that other people are not modifying it for example. One thing you may also want to mention to him is that there are somewhere around 3000 images total and a lot of maps. So while his restrictions from his standpoint may not seem like a very big deal, from my standpoint, it could get to be really annoying (suppose there are 10 image contributors with different policies for example). I think the biggest problem I have is potentially making a promise that may prove difficult keep. What I could agree to: 1) Image is only for the game as crossfire. Image can not be used in any pay version of the game (I don't think there will likely be a pay version, but who knows, and of course, that only changes distribution at that point - old free versions can never be revoked). This does not include things which are at or near media cost redistributions of archives (ie, a cdrom of some archive or say a bunch of linux packages). 2) A notice will be included which says when those particular images are modified, he should be notified, preferably in advance. Note that we can include a version of the images just as we get them from him, and include them as well as a pointer saying that those were the originals. I personally do not want to have to watch to make sure that no one does anything unauthorized with various images. If the image is found to have been modified not to his liking or without notification, at his request we will revert the image back to its original form. 3) While the images may only be for crossfire, he should understand that there are certainly cases where the image may 'leak' out without its owner and restrictions being listed (eg, screenshots or web pages). This may create confusion since the game is generally listed under the GPL. However, my personal understanding is that unless the web page with the screenshot or the like specifically give permission to re-use the image, it is under implicity copyright.
