add support for other languages! is it possible?

Support for other languages, how?

Just the plugin changes the name of the subject into one language. Can I change so that each player sees the name of the item in their game language?

That would require generating those files with ALL of the image names from the game. The server only provides them in English, so you would have to manually translate them if it did add that functionality.

I understand the language file? I would translate.
