finde manage-galleries.php in /plugins/nextgen-gallery/admin and change
$gallerylist = $nggdb->find_all_galleries('gid', 'asc', TRUE, 25, $start, false);
to
$gallerylist = $nggdb->find_all_galleries('title', 'asc', TRUE, 25, $start, false);
When working with large numbers of galleries, you might also want to increase the “25” to a higher number. This will increase the number of rows in your gallery overview page and creates more convenient handling.
Only then you will have to adjust another line that sits right above that from
$start = ( $_GET['paged'] - 1 ) * 25;
to
$start = ( $_GET['paged'] - 1 ) * yournumberhere;
otherwise your pagination will become quirky.
