add foto to conentype for all languages

Hi,

Im using internationalization to have multiple languages. like english french dutch.
Made a basic contentype with title, body and a picture.
So when I add content and translate the instance all is fine, only when I then add add a picture to one of them I want this picture to appear for all languages ofcourse. Not sure how I can accomplish this.
It works when I add the images and then do the translating but, in the future pictures will be added/changed so this needs to works not only uppon creation.
Ideas ?
