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, by joining Transifex, and adding a new team or joining an existing team. If you do this, please email support so we know who you are. If you keep the translation up to date, we will refund your purchase and give you free updates.
