将图片上传到Facebook粉丝页面

我希望我们的Facebook页面的粉丝能够将图像发布到特定的相册 . 虽然该应用程序能够将图像上传到用户时间线，但该应用程序无法将其发布到粉丝页面中的相册（公司的Facebook页面） . 出了什么问题，或者如何更改代码以便我可以跟踪错误 .

在之前的尝试中，我能够使用类似的脚本和永不过期的令牌将图像发布到粉丝页面的墙上，但随后应用程序发布了它，我希望看到用户名 .

<?php
require 'facebook.php';

$app_id = "xxx";
$app_secret = "xxx";
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'cookie' => true
));

$canvas_page = "http://apps.facebook.com/xxx/";
$auth_url = "https://www.facebook.com/dialog/oauth?client_id=" 
. $app_id . "&redirect_uri=" . urlencode($canvas_page)."&scope=publish_stream";

$signed_request = $_REQUEST["signed_request"];

if(isset($_FILES["source"]["name"]))
{
    try {
        $facebook->setFileUploadSupport(true);
        $response = $facebook->api(
        '/ALBUMID/photos/',
        'post',
        array(
        'message' => $_POST['message'],
        'source' => '@'.$_FILES["source"]["tmp_name"], 
        'access_token' => 'xxx'
        )
        );
    }
    catch (FacebookApiException $e) {
        error_log('Could not post image to Facebook.');
    }
}

list($encoded_sig, $payload) = explode('.', $signed_request, 2); 

$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);

if (empty($data["user_id"])) {
    echo("<script> top.location.href='" . $auth_url . "'</script>");
    } else {
    echo ("Welcome User: " . $data["user_id"]);
};


$signed_request = $facebook->getSignedRequest();
$user = $facebook->getUser();
$page_id = $signed_request["page"]["id"];
$page_admin = $signed_request["page"]["admin"];
$like_status = $signed_request["page"]["liked"];
$country = $signed_request["user"]["country"];
$locale = $signed_request["user"]["locale"];

echo "<br>user id = $user";
echo "<br>page id = $page_id";
echo "<br>page admin = $page_admin";
echo "<br>like status = $like_status";
echo "<br>country = $country";
