404 if no index

[eluser]happyeddie[/eluser]
Hi,

in my controller I can't pass any parameters to index() without it getting a 404.
If if I do this however, foo/index/234 then there is no 404.
All methods within my classes work fine. bar/thunk/234 works fine.

My controller looks like this

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class View_images extends CI_Controller {


public function __construct()
{
  parent::__construct();
}

public function index()
{
  echo $this->uri->segment(2);
}

My .htaccess file looks like:

Code:

RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

Any help will be appreciated. Thanks.
