Facebook Publisher Correct Metadata Information

The current Facebook Publish Plugin uploads the picture but does not change the date of the picture or the photo description according to the Metadata information present on it. It would be the same to upload the picture through the web browser to Facebook, no metadata information is used and the user has to input this by itself for each picture. So I propose that the Publisher plugin do that automatically, providing a useful tool to the user to share its photos with correct dates and descriptions.
