Adding Media to Buddypress then users sharing to social media.... pls help

Pls Help!

I am coming to the end of my teather.

All i want to do is to be able to add pics/vids/ to buddypress posts and then have users be able to share to Facebook / G+ / Twitter. It may sound simple but i am getting nowhere with it for whatever reason.

Pls Pls Pls... what two plugins will work together to do this? Whatever i try the buddypress post image is not showing on the FB wall that it was shared to. I just want the buddypress post to be replicated on social media as it was intended. same txt and same image.... simple.

Pls help as i have spent days on this.
