You can easily change the Radiant Photo language by following the steps below:
- Launch the Radiant Manager application.
- Click the gear icon in the lower left corner to set the language.
- Restart Radiant Manager and Radiant Photo.
- Voila! Radiant Photo now speaks your language of choice. It's like magic, but without the rabbit in the hat.
Normally Radiant Photo will detect your system language, but this is an override.
