Pictures are not the only meduim of exchange for words.

For instance:
A blank peice of 8.5x11 paper is worth 50 words. Legal-size is 60.
Strawberries are 1.5 words an ounce.
In the 80s, a Commodore 64 was 12,000 words, but is now worth less than the letter x.
On eBay, Carl Sagan's eyelash sold for enough words to ring the planet Earth 3 times.
Bacardi 151 trades at 50 words for the first shot, 1,500 for the second, and for the third takes away your power of speech.
An orgasm is worth only 4-10 words, but each is usually repeated upwards to 100 times.
