Twitpic API 2 Upload and Post

[i_am_turner]

Hi all, I've got a bit of a problem with the Twitpic Api v2 upload. I'll post my code below. The picture with the message uploads to Twitpic, but it's not being posted to Twitter. Anyone have any ideas or experience with this? Thanks.

 

<?php

include 'EpiCurl.php';
include 'EpiOAuth.php';
include 'EpiTwitter.php';
include 'secret.php';

require 'class-xhttp-php/class.xhttp.php';

xhttp::load('profile,oauth');
$arvin = new xhttp_profile();

$arvin->oauth($consumer_key, $consumer_secret, $_COOKIE['oauth_token'], $_COOKIE['oauth_token_secret']);

// Generate OAuth Header
$authorization = $arvin->get_oauth_header('https://api.twitter.com/1/account/verify_credentials.json');

$data = array();
$data['headers'] = array(
'X-Auth-Service-Provider' => 'https://api.twitter.com/1/account/verify_credentials.json',
'X-Verify-Credentials-Authorization' => $authorization,
);

$data['post'] = array(
'key'    => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxx',  # Twitpic App API key
'message'=> $message,      # Twitter status
);

$data['files'] = array(
'media'  => $image_url,
);

$response = xhttp::fetch('http://api.twitpic.com/2/upload.xml', $data);

if($response['successful']) {
echo $response['body'];
} else {
print_r($response);		
}

?>
