Modify code Facebook Auto-Reply Script to send images and third-level replies

Hello! I am looking for a developer that can customize a Facebook Auto-Reply Script. The script runs with PHP, Cron Jobs and FACEBOOK API GRAPH. It already has most functions that I want and need, but I specifically need it to be able to send images automatically through private message depending on the post. So for Post A send Text A and Image A. For post B send Text B and Image B. It would just require some modifications. Also to add third-level or fourth-level continous replies. I am also open to suggestions. * The script and its functions will be provided through Private for the developer to see the code. Also I have access to the original creator/developer who could maybe help answer some questions.
