" It is not literally true that a picture is worth a thousand words. Most people will not see what is in a picture, or will see it through the most readily available visual cliches. It takes training and an analytical vocabulary to talk about what is in a picture, and to know what to look for. A picture is worth a thousand words only for those who already have internalized an adequate vocabulary. "
