The Image Viewer user interface and documentation is being translated by a world-wide volunteer community. You are welcome to participate.

There are many languages for which translations are still needed.

To start translating you will need to create an account and join the translation team for your language. This will give you the ability to upload new translations.

You can chat with GNOME translators in #i18n:gnome.org on Matrix or #gnome-i18n on irc.libera.chat. People on the channel are located worldwide, so you may not get an immediate response as a result of timezone differences.

Alternatively, you can contact the Internationalization Team using GNOME Discourse.
