Translating of "previous" | "next" link

Hi,

it would be good if you add a support for translation to "previous|next" link.

Code from module :

$vars['next_prev_links'] = '<a onclick="$.galleria.prev(); return false;" href="#"><< ' . t('previous') . '</a> | <a onclick="$.galleria.next(); return false;" href="#">' . t('next') . '>></a>';

Thanks :-)
