How can I insert a flash intro in my CI website?

[eluser]wiz88[/eluser]
This is what I have at the top of welcome.php
<?php
class Welcome extends Controller {

function Welcome()
{
parent::Controller();

$this->load->helper('url');
$this->load->helper('form');
$this->load->library('validation');
// session_start(); //start session for captcha
/*$this->load->model('captcha_model'); //load captcha model
$this->load->scaffolding('subcategory');
$this->load->model('Leftbar');*/
}

function index()
{

Where do I put the code?
OH and to answer your question we sell flash intros with our sites. Girls seem to love them.
Check it out:

This auto goes to index.php after you get there and click on the logo the index.php
goes away. I never really used PHP. I'm old school what can I say.
