Facebook: publish image to page album with app access token - php

Question

How do I give a Facebook App permission to post images to a Facebook Page album?
This is the code I use:
$args = array(
'image' => '#' . $img,
'aid' => $album_id,
'no_story' => 1,
'access_token' => $app_access_token
);
$photo = $facebook->api($album_id . '/photos', 'post', $args);
This is the error I get:
Uncaught OAuthException: A user access token is required to request this resource.

Here is the code I use to publish a photo to an album on Facebook. I hope it'll help.
<?php
include '../src/facebook.php';
$config['appId']='app_id';
$config['secret']='API_KEY';
$config['fileUpload'] = true;
$param['redirect_uri']='your_redirect_url';
$param['scope']=',publish_stream,user_photos';
$facebook=new Facebook($config);
$userid=$facebook->getUser();
if($userid){
try{
$args = array(
'image' => '#' . $img,
'message'=>$message,
);
$photo = $facebook->api('/'.$album_id . '/photos', 'post', $args);
}
catch(FacebookApiException $e){
echo $e->getMessage();//Get OAuth Error
}
else{
$loginUrl=$facebook->getLoginUrl($param);
echo "Please <a href='$loginUrl'>Click Here</a> To Login";
}
?>

Just in case any user stumbles upon this post , to resolve this error
1> $facebook->setaccesstoken() to facebook page's access token . The facebook page access token is available by issuing $facebook->api('/user_id/accounts'), here user id is the id of page's admin .
2> After setting access token you can use the facebook->api to post the photo to album using album id
$facebook->api('album_id/photos', 'post', array( 'source' => '#'.$photo ));
