I am not an expert in licences but here is how the GPL defines 'source code': The source code for a work means the preferred form of the work for making modifications to it. That has nothing to be with being a text file so my understanding is that images are also 'source code'. For images coming from a LGPL project, the solution is simple. You project should be able to use them as long as they are not statically linked in the program. Do not forget that you should NOT REMOVE THE LGPL licence. The safest way to do it is to distribute your program and the LGPL icons in 2 different packages. The situation is more complex for the GPL because GPLed codes cannot be mixed with non-GPL codes even if their are not statically linked together. The only escape I can see is that the non-GPL/GPL clause is not applicable to the data used by the application so that would be ok to reuse icons if they are considered as input data for you application. But once again, you would have to distribute the icons under the GPL. ps: I am not an official member of the GIMP team so the opinions expressed in that email are not official. _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
