Can anyone shed some light on my problem?

<?php

$config = array();
$config['appId'] =  "foo";
$config['secret'] = "bar";
$config['cookie'] = true;
$config['fileUpload'] = true;

$facebook = new Facebook($config);

$eventParams = array(
    "privacy_type"  => $this->request->data['Event']['privacy'],
    "name"          => $this->request->data['Event']['event'],
    "description"   => $this->request->data['Event']['details'],
    "start_time"    => $this->request->data['Event']['when'],
    "country"       => "NZ"
);

//around 300x300 pixels
//I have set the permissions to Everyone
$imgpath = "C:\\Yes\\Windows\\Path\\Photo_for_the_event_app.jpg"; 
$eventParams["@file.jpg"] = "@".$imgpath;

$fbEvent = $facebook->api("me/events", "POST", $eventParams);

var_dump($fbEvent); //I get the event id

I also have this in my "scope" when the user is asked to Allow the app to post on his behalf: user_about_me,email,publish_stream,create_event,photo_upload

This works. It creates the event with all the details I have specified. EXCEPT for the event image.

I have been to most of Stackoverflow posts related to my problem but all of them are not working for me. (EG: http://stackoverflow.com/a/4245260/66767)

I also do not get any error.

Any ideas?

THanks!
