Facebook Group Poster and Scheduler

I need a Facebook Group Poster and Scheduler project. Features: Manage unlimited number of accounts. Post to all groups that account joined (Unlimited number of groups) (The post should be: upload picture with text, no link with picture thumbnail). Works through Access Token (I just have to enter an access token, no application id, application secret, just Access Token ID). Admin Panel where to: Schedule Posts (set time where to make a post to all groups). Manage FB Accounts (Add, Edit, Remove). Manager Users (Add, Edit,Remove) (Users can post and manage accounts the same as admin but they can't add/edit/remove any user). Set delay time between posts. Others (we'll talk them in private) Exemple of script with access token: [login to view URL] It does not upload images anymore, returns an error. I want something similar but more advanced as described above.
