One solution would be to allow users to upload photos to your own server and then allow the user to submit the photos to facebook.

$file = 'path_to_image'; // Dont forget to add $_SERVER['DOCUMENT_ROOT'] $photo_details['image'] = '@' . realpath($file);

$upload_photo = $facebook-api('/me/photos','post',$photo_details);

The photos will be uploaded to your application's album. Alternatively you can substitute "/me/photos" for "/$album_id/photos", if you wish to upload your photos to a specific album.

When you upload several photos ( even if there is some delay between uploads ) the story in the news feed will contain previews of three of the recently uploaded photos.
