The source form, for the GPL, is usually clear when you look at an individual work (and don't try to generalize it to death): it's the form actually used to modify. For the first: if it's the form that would be used if the author wanted to modify the image further, yes. For the latter: probably not, but that isn't what determines whether it's source or not. I disagree that the GPL is unclear in the above cases. You may not necessarily want to require source for all media, though, regardless of whether "source" is clear. (There's been a repeated conversation wrt. source distribution and the DFSG: what should Debian require for things like images, fonts and movie clips? There isn't a strong consensus, yet.) I agree that this license is a poor choice, though. It's very unclear and poorly written/translated. -- Glenn Maynard
