Download Event Gallery Core.
Event Gallery ships with an English and a German translation. Sometimes people send over translation files for different languages. I can't bundle them with Event Gallery but I'll add them to this section so everybody can benefit.
Please note that I will not provide any support for those files. Do never add those files directly into the components folder. They'll get removed with every update.
Please read this article to get familiar how to use language files correctly: Customize Language Files
Translations are also hosted on GitHub. You can create your own translation package by following the instructions here. Feel free to contribute with pull requests. https://github.com/svenbluege/eventgallery-translations
