Sorry I forgot the part where I edit, so I include the whole function.
Maybe you could look inside the ‘wp-pagenavi’ especially anchor tag attributes.

[ Moderator note: pre works but please use the code button or backtick character instead. ]

<?php

	if( 0 < $total && 0 < $page )

		remove_query_arg('page');

		$options = get_option('file_gallery');
		$out = array('<span class="current">' . $page . '</span>');

		if( ! isset($options['pagination_count']) || empty($options['pagination_count']) || 0 >= $options['pagination_count'] )
			$limit = 9;
		else
			$limit = $options['pagination_count'];

		$c = 0;
		$l = $limit;
		$end = false;
		$start = false;
		$current = $page;

		$sides = ($limit - 1) / 2;
		$sl = ceil($sides);
		$sr = floor($sides);
