I love Munch's works..

No one paints a good anxiety driven, Nordic depression like Munch [:)] But yes, he is quite something.

I took these famous pictures (all expired copyrights) on Wikipedia... I suppose they are free from photographer copyright, no ?

Yes, well, sort of. Engineers and mathematicians love to simplify. Lawyers and legislators do not. Wikipedia pays a lot of attention to copyright, so mostly you will be fine. However, sometimes there could be for instance a CC BY NC that will require crediting the photographer or other limitations. And some rights may be in dispute. Munch's copyright expired January 2015, but until then his relatives kept pretty tight reins on the use of his art. Stricter than most people's perception of what would be legal, and stricker than many Internet users ever would respect so many "illegal" copies could be found online. Also, things change. When the EU extended the copyright period after the death of the artist, it was jokingly referred to as the greatest resurrection in almost 2000 years. Long dead artists suddenly found themselves having a renewed copyright to works long since expired. But yes, the short answer is Wikipedia/Wikimedia Commons are usually available for use. But do pay attention to possible commercial limitations and the need to credit photographer.

The actual model of Munch's Scream was not included in the upload to SF 364. That is an example of a CC BY NC licence. The Scream is now included in an imaginary art gallery as a sort of concept to how SH3D and FurnitureLibraryEditor can be used to include copyright and other information. The file includes a couple of paintings stolen from me (in fact, they took absolutely everything worth more than € 100, with a truck). I would love to get them back, maybe a SH3D user will know where they are. And for those less honest, nope, nothing left to steal here...[:(]
