Video Gallery Pro's administrative interface is only available in English. All of the text that is presented to web site visitors can be changed, including to other languages.
Most text is contained in the config2.lib.php file within the config sub-directory. This file contains instructions on how to change any text values. Customizing how Video Gallery Pro works contains additional information on changing the config2.lib.php file.
It is also possible to be text directly into the Video Gallery Pro templates. These also can be changed.
