Multisite, one administration

dear developers,

wonderful plugin, you made a great work, thank you

I have a multisite installation (Version 3.4.2), using WP as CMS for three different languages. The path for Nextgen (Version 1.9.7) is set ‘wp-content/uploads/nextgen/’ under Network options. Anyway, I can´t admin my galleries for all three languages. Therefore I used a hook

Nextgen, nggallery.php, line 229

function define_tables() {
global $wpdb;

// add database pointer
$wpdb->nggpictures = ‘wp_ngg_pictures’;
$wpdb->nggallery = ‘wp_ngg_gallery’;
$wpdb->nggalbum = ‘wp_ngg_album’;
}

but after every update, my galleries are lost.
Is there any other way to control three lamguages with a single nextgen administration?

Thank youn very much for your help.

With best regards
ll.
