Changing localization of an image

Hey People, I have a need to change the localization of an instadmg created image after it's been built. I see that in the instadmg script it sets an iso code. # Default ISO code for default install language. Script default is English. ISO_CODE="en" I'm assuming that this is used by the installer to select which bit's are installed. Can anybody confirm how this is used exactly? Also If anybody knows all the things to change an OS image from English to another language please share.. I'm writing a script that creates a user and sets the language of the OS on first boot. Currently doing some tests with the following commands but I'm not convinced thats all I need. changing from english to japanese defaults write NSGlobalDomain AppleLanguages "(ja, en, fr, de, es, it, nl, sv, nb, da, fi, pt, zh-Hans, zh-Hant, ko)" defaults write NSGlobalDomain AppleLocale "ja_JP" Thanks, Blake
