How do langauge translations get added.
The language translations are maintained at Transifex. Transifex is a tool to manage translations online, and Joomla language files can be generated from Transifex.
You can add a translation for the gallery, or help with an existing translation. Please join Transifex, and add a new team, or join an existing team. If you do this, please email Ignite Gallery support too.
