Re: license question
From GNU GPL FAQ available at http://www.gnu.org/licenses/gpl-faq.html#GPLOutput , the output generated with a program distributed under GNU GPL isn't covered by GNU GPL license and its copyright belongs to the people who made it.
Thus, the copyright of the images generated by Sweet Home 3D should belong to the user who made them and he can choose to use these images in a closed project or in a non-free project.

But the same FAQ also states that when a program translates its input into some other form, the copyright status of the output inherits that of the input it was generated from.
Then, I guess the copyright of images generated by Sweet Home 3D should also depend on the copyrights of the furniture models displayed in it.
As the 3D models shown in the default catalog of the program and in the 3D models page http://www.sweethome3d.eu/importModels.html are distributed either under GNU GPL, Free Art License or Creative Commons Attribution license, the images generated by Sweet Home 3D that displays these 3D models can be distributed freely even for commercial purpose.
But I'm not perfectly sure that these images can be distributed under a closed license.

As a conclusion, I would recommend that you distribute images created with Sweet Home 3D under a free license with your additional copyright, along with your project and its closed/non-free license.

As I'm not a lawyer, any advice will be read with great interest. ;-)
