Upload picture on Flash site, send in e-mail via PHP form.

I am building a Flash site for a modeling agency.  They need a form on the site that allows both information (name, height, etc.) to be e-mailed along with an uploaded photo to the agency e-mail address.

I know how to use PHP to upload a photo to the server.  But I want to know how to actually have the photo e-mailed as an attachment via the PHP e-mail.

The PHP script I got from this site to upload to the server is:

<?php
$target_path = "./uploads/";
$target_path = $target_path . basename( $_FILES['Filedata']['name']);
move_uploaded_file($_FILES['Filedata']['tmp_name'], $target_path);
?>

How does that need to be changed to make it e-mail instead of upload to a folder on the server?

thanks!
