can images do what words do?

Images can do much more than words can do. A picture is worth a thousand words. For example when people who are pro life are holding up signs against abortion, they mostly use pictures to persuade people to believe what they believe in. A picture of a mangled infant is going to affect a person more than an essay on the subject. It is also a quick an easy way to get their point across. (This in no way reflects my feeling on the subject of abortion.)
