When I am in admin mode - and I select the edit files link next to the album I want to edit - the pictures are listed in file name order. I want to have the images listed in order of upload so that I can prune and delete the older images. Is this possible?
In editpics.php, change
$result = db_query("SELECT * FROM {$CONFIG['TABLE_PICTURES']} WHERE aid = '$album_id' ORDER BY filename LIMIT $start, $count");
to
$result = db_query("SELECT * FROM {$CONFIG['TABLE_PICTURES']} WHERE aid = '$album_id' ORDER BY mtime DESC LIMIT $start, $count");
That should do the trick.
