Have you ever noticed how challenging it can be to describe what you see to a person not presently with you? You could be witnessing some spectacular spectacle or some terrifying sight, but try as you might to communicate your experience, your words seem weak.
However, send a photo of what you see, and suddenly there's mutual understanding. The image instantly conveys context and meaning. You've heard the phrase "a picture is worth a thousand words" repeated time and again. Cliché notwithstanding, this phrase continues to ring true in human communications.
