In this post http://piwigo.org/forum/viewtopic.php?id=27833 I was told how to assign a rep representative to an album - the solutions here work only if the photos are in the album.  I have many parent albums that have only other albums in them.  These parent albums are having the representative set for them randomly and then I see no way to change them.  I have searched for how to do this but all I can find is basically what was in the post listed above, nothing works for this parent album situation.  It is important for me to change these because many of the auto selected ones are not appropriate and theses parent albums are the first presented to the visitor.  Please help me find where to change the parent  album representative.

Thanks in advance for your help.
