want to share activity feed to facebook and other social networks but confused

Hey. I've tried the Facebook plugin before for social sharing, but it only seemed to share to my own timeline, as compared to a general sharing principle that my users could share from the buddypress to facebook.

i'm currently working with Super Socializer, but that doesn't give me the images that I upload properly nor link to the Activity feed. is this doable?

Essentially, I want something that shares to Facebook or other social network from an Activity feed post, which then brings beings back to the profile page of the user that posted the feed. am I not understanding how these things work properly?
