Solved it.
So, except for making a small addition to the WEB-INF\config\languages\locales.properties, adding the new lang file to the same folder, adding a reference to some file i no longer remember where it was (for admin interface purposes), creating a image folder for the files i was sloppy and didnt notice that the css file for the new languagespecific images had a reference to the language for each image file. :lol:
Great work by the away with jForum - i just love the way it can be customised! And i sure will return with that language of mine when done..
