A picture is worth a thousand words
"A picture is worth a thousand words" is an English language adage. It refers to the notion that a complex idea can be conveyed with just a single picture, this picture conveys its meaning or essence more effectively than a description does.
In March 1911, the Syracuse Advertising Men's Club held a banquet to discuss journalism and publicity. In an article on The Post-Standard covering this event, the author quoted Arthur Brisbane as saying: "Use a picture. It's worth a thousand words." 
Early use of the exact phrase appears in a 1918 newspaper advertisement for the San Antonio Light, which says:
One of the Nation's Greatest Editors Says:
One Picture is Worth a Thousand Words
The San Antonio Light's Pictorial Magazine of the War
Exemplifies the truth of the above statement—judging from the warm
the reception it has received at the hands of the Sunday Light readers.
The modern use of the phrase is generally attributed to Fred R. Barnard. Barnard wrote this phrase in the advertising trade journal Printers' Ink, promoting the use of images in advertisements that appeared on the sides of streetcars. The December 8, 1921, issue carries an ad entitled, "One Look is Worth A Thousand Words." Another ad by Barnard appears in the March 10, 1927, issue with the phrase "One Picture Worth Ten Thousand Words", where it is labeled a Chinese proverb. The 1949 Home Book of Proverbs, Maxims, and Familiar Phrases quotes Barnard as saying he called it "a Chinese proverb, so that people would take it seriously." Nonetheless, the proverb soon after became popularly attributed to Confucius. The actual Chinese expression "Hearing something a hundred times isn't better than seeing it once" (百闻不如一见, p bǎi wén bù rú yī jiàn) is sometimes introduced as an equivalent, as Watts's "One showing is worth a hundred sayings". This was published as early as 1966 discussing persuasion and selling in a book on engineering design.
Despite this modern origin of the popular phrase, the sentiment has been expressed by earlier writers. For example, Leonardo da Vinci wrote that a poet would be "overcome by sleep and hunger before [being able to] describe with words what a painter is able to [depict] in an instant." The Russian writer Ivan Turgenev wrote in 1861, "The drawing shows me at one glance what might be spread over ten pages in a book." The quote is sometimes attributed to Napoleon Bonaparte, who said "A good sketch is better than a long speech" (French: Un bon croquis vaut mieux qu'un long discours). This is sometimes translated today as "A picture is worth a thousand words."
