ImageGlass v1.5 final will be released this August. This is the most awesome version until now. An important feature, changing language, will not be perfect without your support!
The following link is a sample of ImageGlass language pack. You just download it, and open by any editors, such as Notepad, and replace 'xxxxxxx' string to your words.
Don't forget to send me your edited file again in Facebook or my email firstname.lastname@example.org
