I administer a Facebook that is mainly about members posting and commenting on photos.  Most members go the group wall and post photos directly to the group gallery. If a post is inappropriate, as admin I can remove it.  However, some members, instead of posting directly to my group, have instead shared photos to my group from albums on their own page. I am unable to delete those posts from my page.  At the bottom right of their post, where it would normally offer remove this photo as one of the admin options I see only Download and Report/Remove Tag as my options.  Even removing the posters from the group and blocking them did not remove their shared photos. I can't believe that I am unable to remove content from my own group but so far I can't find any way to get rid of these shared posts. Can anyone help? 
How do I delete posts to my Facebook Group that are links from another user's Facebook page?
