All answers above are wrong! There is only one way to create the Cover Image:

Create The Event:

$eventData = array(
    'name' => 'Event Title',
    'start_time' => 'StarttimeInCorrectFormat',
    'description' => 'Event Description'
);
$fbEvent = $fb->api('/PAGE_ID/events/', 'post', $eventData);

Update the Event using the ID from above:

$cover['cover_url']     = 'http://urlToCoverImage.jpg';
$eventUpdate = $facebook->api( "/" . $fbEvent['id'], 'post', $cover );

return true or false.

And thats it. Cover is in.
