Optional media sources

The editor can connect to Pexels, Pixabay and Unsplash when configured. Their image licenses, attribution requirements and API terms are separate from Rigel's software license. Availability of an image in a provider search is not a blanket permission to reuse it.

Licenses and notices

Each component retains its own copyright and license; acknowledgement does not replace the notices required when distributing software or assets.
