Gallery AutoPost

Hello guys, i am using the FAuto Poster plugin on my website, i was wondering if it is possible to auto post photos from gallery in wordrpress to facebook.
All what i am trying to do is this:
My client wants to add a photo in the gallery at wordpress and when he does this the photo to be automatically posted to his profile / page in facebook.
I tried to do this but i got no results till now and started to wonder if this is possible at all.
If it is possible please give me some advice / help on how to continue.

Thanks in advance 🙂
