A picture tells a story just as well as, if not better than, a lot of written words.
Images can also warn us or give us clues about to what’s to come.
History
The expression "Use a picture. It's worth a thousand words." appears in a 1911 newspaper article quoting newspaper editor Tess Flanders discussing journalism and publicity.A similar phrase, "One Look Is Worth A Thousand Words", appears in a 1913 newspaper advertisement for the Piqua Auto Supply House of Piqua, Ohio..
We can convey emotion by adding a picture
As humans we are largely responsive to visual cues (pictures) whether we like to admit it or not.Pictures have the ability to make us feel happy, excited, disgusted, and curious among other things.
We can remember a famous brand just by looking at their image and can even reminisce 10, 20, 30 years into the past to a moment in our lives where we were affected emotionally by a specific event simply by looking at an old picture.
