On a Drupal 7 installation I have an image gallery (set up with the media gallery module). I set the upload destination to private to protect those images for anonymous users. Unfortunately it turned out, that the performance of private images is that poor, that the gallery became quit unusable.
So I decided to switch the destination to public for the node type. But as there already exist nodes of the mentioned type (I assume that my be the reason), the options of the node type's filed, where to set the destination is greyed out:
Is there any way to change the destination for existing nodes?
