Following is the code that works fine if I am passing /pageid/feed to facebook->api, but when I change it to upload the image directly to my Facebook photo album, it will not work. Kindly let me know what I am doing wrong in the following code:

// Works fine
$status = $facebook->api("/194458563914948/feed", 'post', $attachment);

// Does not work
$status = $facebook->api("/196878530339618/photos", 'post', $attachment);

    <?php

require 'src/facebook.php';

$app_id = "332267477347";
$app_secret = "xxxx";

$facebook = new Facebook(array(
 'appId' => $app_id,
 'secret' => $app_secret,
 'cookie' => true,
 'fileUpload' => true,

));

$facebook->setFileUploadSupport(true);  


$user = $facebook->getUser();
//echo $user;

if(($facebook->getUser())==0)
{
 header("Location:{$facebook->getLoginUrl(array('scope' => 'photo_upload,user_status,publish_stream,user_photos,manage_pages'))}");
 exit;
}
else {
$accounts_list = $facebook->api('/me/accounts');
echo "i am connected";
}
  $valid_files = array('image/jpeg', 'image/png', 'image/gif');


//to get the page access token to post as a page
foreach($accounts_list['data'] as $account){
      if($account['id'] == 194458563914948){      // my page id =123456789
        $access_token = $account['access_token'];
        echo "<p>Page -- Access Token: $access_token</p>";

The path you are using /406221796071956/photos is wrong and that's why it does not work.

The reason that this path is wrong, is that 406221796071956 is the id of a picture, see for yourself, the Graph API Explorer for 406221796071956 says:

"type": "photo"

If you want to publish to that album then use /196878530339618/photos, since it's the album: Graph API Explorer for 196878530339618

"type": "album"

Edit

Please refer to https://developers.facebook.com/docs/reference/api/album/#photos for adding photos to an album.

2nd Edit

According to the documentation of the Album object:

can_upload

Determines whether the UID can upload to the album and returns true if the user owns the album, the album is not full, and the app can add photos to the album

So you need the album not to be full, to be the owner of the album and have the right permissions for uploading.
