[TYPO3-dev] Extension enable translation for a field

[Ronald Renfro]

Hi List,

I am developing a simple extension that extends the pages db table by  
adding an additional media field. When I create a translation of a  
page the new field is not displayed. How can I specifiy in my  
extension that this field can be translated e.g. every translation of  
a page can have a different background image.

Thanks in advance.

Best regards
Ronald
