Note: This tutorial refers mainly to the development build of Zenphoto since localization/translation is a work in progress. Zenphoto includes a file "zp-core/functions-l18n.php" that contains a prefdefined list of languages and their related locales. Check this list to be sure your language is included. If it is not there, let us know and we will add it.
What should I know before starting a translation?
All existing complete or uncomplete translations are included in the Zenphoto release package. The language selector on the backend options indicates the status of a current translation.
It would be good if you were quite confident in written English and quite comfortable with Zenphoto itself and with web developement in general, although no coding is required to make a translation.
Keep in mind that if you volunteer to make translations there will be the need of updating the languages files at least (...)
