I'm looking for the same thing. I can't quite work out, though (primarily because of my non-existent German!) whether Pony Gallery is Joomgallery, or whether the latter is a separate, ongoing project (I think I saw somewhere that Joomgallery hasn't let been released)
I guess I'm just going to have to install Pony Gallery and see if the feature exists, though can anyone shed any light?
I havent quite been able to figure out if this is what we have been looking for. You can use google to translate the site for you, and then you can browse the site with google continually translating everything for you.
er.... I downloaded it anyway, and hey presto the component is in English!!!
Komponent is ... Component! Modul is... module!
and the back end is in English by default! Sprachdatei means language information, no need as those clever Germans have anticipated our English speaking needs and made the component English already....
guys, you need to be a little more adventurous ...
