The plug-in supports English and French but it is possible to add other languages based on the ApplicationPlugin_en.properties template.

Based on these instructions , the addition of a language can be done as follows:
1-unzip the PhotoVideoRendering-VERSION.zip file
2-transform the .sh3p into .zip
3-paste your file ApplicationPlugin_LANGUAGE.properties
4-transform the .zip into .sh3p

For any additional language integration directly to the plug-in for future versions, you can contact me .
