This topic is for anyone who wants to improve zenphoto. I had opened a post on gihub to add new languages. If you or someone in your circle spoke Arabic, Portuguese, Hindi, Greek, and you wished to improve the translation for the next version of zenphoto please visit this pages :

Please see my last comment on your original ticket. I think that gives a better overview for possible contributors.

Please make sure on your repo and your translations that only official files are included. You currently have included the 3rd party zpBase theme in your repository. This will cause issues once you will submit pull request to include your translations. Basically we would need to refuse them if that is still present.

zpbase as a 3rd party theme should be setup for theme based translation instead (sadly its author is currently away so that is probably not going to happen).

OK I take note of this information and I open one ticket per language and I delete zpbase.

Thanks, great. Looking forward to your translation contributions.
