Sort of. You can set the language selector to "HTTP Select Language". Then the language is taken from the browser's prefered language list. (Of course, only for those languages that have translations!) So your visitors would see Zenphoto in their perferred language and you would see it in yours.
Yes, there is if you enable the seo_locale plugin.

Thanks. But I still don't get it. Could you help me to locale below link to another language?
