The Facebook social network ensures that, whether you haven't seen a person within the last ten years or ten minutes, everybody can remain connected. Billions of messages are shared through Facebook on any given day, but while we are often only directing our correspondence with one or a small group of people, it's often the case that everybody can read it. In these instances, a private inbox message may be necessary, but if you want to have some fun with it, you could try a new Chrome extension allowing you to secretly hide messages within images. While perhaps not an immediately reassuring mode of obscuring a message from prying eyes of others, the extension, developed by a computer science student at Oxford University, does have an element of mischievousness to it, and will have your Facebook friends scratching their heads as to why you're consistently posting plain images of your food. (Oh, wait..)
