Slightly off topic but that's a terrible definition of human rights (and being in nice crisp text makes this immediately apparent).

A far better one is, "Human rights are political conditions necessary of the life of a morally autonomous being." Tyranny and democracy are both "political conditions", as is "the rule of law" and various other things. One useful thing about this definition is that under it rights are both natural and inalienable: a right may be violated (a condition may not be met) but the necessity of certain political conditions for moral beings to be able to make their own moral choices (moral autonomy) cannot be removed.

So not only does text enable us to present ideas more succinctly and precisely than images, it allows us to argue about them effectively, and to have those arguments remain somewhat accessible for thousands of years. Images can be used as components of an argument (I've never published a scientific paper without graphs) but without the accompanying text the argument is woefully incomplete, whereas text alone is capable of sustaining a vast range of arguments without any accompanying images.
