#21 pictures' copyright - just to be sure

[Rattala]

Hi, just to be sure, I know the software is open source but can developers confirm that pictures rendered by means of Apophysis software are free from any copyright constraints and bindings so that I can use those pictures either for personale or commercial use ?
Is this valid also for Apophysis 3D hack.exe?
Thanks for clarifications and many thanks for your great application.
