Topic: Graphics from http://reinerstileset.4players.de/englisch.html

Using the graphics from http://reinerstileset.4players.de/englisch.html came up in the IRC channel last week.
We were looking in particular at the trees he has done. Trees are present in a few sections on the site - there are some growing in the animated section. It's an interesting site to dig around.
The licensing terms for the graphics lack desirable hard edges though: http://reinerstileset.4players.de/readmeE.html
I took an action to contact Reiner and clarify if we can release his graphics under the GPL. The short answer is that we can't re-license the graphics under the GPL but we can (if we note reiners license terms with the files) distribute and modify them almost without restriction.
Here is my email to Reiner:
And here is his reply:
I think Reiners intention there is clear - he even says on his site that you have "full ownership" of the graphics once they are embedded in your game.
However, obviously, so long as Reiner retains some hold over the usage of the files (namely that they may not be extracted from the game and hosted in gallery form akin to his website) then we are not totally in ownership of the graphics and thus not able to truly release them under the GPL.
We are however free to use and distribute any of his graphics as part of our software. Modification and distribution ad infinitum is fine - Reiners restriction is that the graphics are not extracted into a gallery form.
I would suggest the best course of action be as follows: 1) Create a separate directory for graphics from Reiners site. 2) Include his licence / README / above letters as the license for files in that directory. 3) Note that that directory is under a separate license in our main licence file.
Note that we would also have to refrain from including Reiners graphics in any gallery pages we might have that dump all the graphics we use.

thanks for your work and effort; Nevertheless we had some licensing issues related to distributions before and so we will not include graphics over which we do not have full license information available.
As pretty as Reiners graphics might be, as long as he doesn't contribute them to widelands under the GPL license, we will not include them.
I fully agree though that he makes his intention quite clear, but nevertheless this is more trouble than it's worth.
