Facebook/Contacts/Profile Pics
Recently all of my emails and contacts are showing their profile pictures, even if we're not friends on Facebook. This is really annoying, only because it's added images I don't need/want to see. Is there a way to prevent this from happening, and remove all of the current profile pics of those in my contact list? It's happening on all of my devices (macbook, ipad, iphone). Any help would be appreciated.
