add_filter ('rewrite_rules_array', 'RTS_pics_rewrite');

is correct.

have you also added the ability to recognise the %pics% tag you just added, using the query_vars
filter?  You also might want to not use + to join your two arrays together.  Seeing as the rewrite
rules array can be passed by reference you can just add it that way.  Try this and see if it works:

add_filter('query_vars', 'RTS_query_vars');
add_filter('rewrite_rules_array', 'RTS_pics_rewrite');

// Define the language query variable.
function RTS_query_vars($vars)
{
	$vars[] = 'album';
	return $vars;
}

function RTS_pics_rewrite(& $rewrite)
{
	$keytag_token = '%pics%';
	$wp_rewrite->add_rewrite_tag($keytag_token, '(.+)', album=');
	$keywords_structure = $wp_rewrite->root . "pics/$keytag_token";
	$rewrite[] = $wp_rewrite->generate_rewrite_rules($keywords_structure);
}

Hope this helps, or at least gives you a starting point,

Cheers,

Jamie.
