pickle (n.)youdaoicibaDictYouDict[pickle 词源字典]
c. 1400, probably from Middle Dutch pekel "pickle, brine," or related words in Low German and East Frisian (Dutch pekel, East Frisian päkel, German pökel), of uncertain origin or original meaning. Klein suggests the name of a medieval Dutch fisherman who developed the process. Originally a sauce served with meat or fowl; meaning "cucumber preserved in pickle" first recorded 1707, via use of the word for the salty liquid in which meat, etc. was preserved (c. 1500). Figurative sense of "sorry plight" first recorded 1560s, from the time when the word still meant a sauce served on meat about to be eaten. Meaning "troublesome boy" is from 1788, perhaps from the notion of being "imbued" with roguery.[pickle etymology, pickle origin, 英语词源]

Pict (n.)youdaoicibaDictYouDict
an ancient people of Great Britain, late 14c., from Late Latin Picti (late 3c., probably a nickname given them by Roman soldiers), usually taken as derived from picti "painted," but probably ultimately from the Celtic name of the tribe, perhaps Pehta, Peihta, literally "the fighters" (compare Gaulish Pictavi, a different people, who gave the name to the French city of Poitiers). They painted and tattooed themselves, which may have suggested a Roman folk-etymology alteration of the name. The Old English name for the people was Peohtas.
In Scottish folk-lore the Pechts are often represented as a dark pygmy race, or an underground people; and sometimes identified with elves, brownies, or fairies. [OED]

Picture post-card first recorded 1899. Phrase every picture tells a story first attested 1900, in advertisements for an illustrated life of Christ. To be in (or out of) the picture in the figurative sense dates to 1900.

Expression a picture is worth a thousand words, attested from 1918, probably was from the publication trade (the notion that a picture was worth 1,000 words is in printers' publications by 1911). The phrase also was in use in the form worth a million words, the form used by American newspaper editor Arthur Brisbane (1864-1936) in an editorial much-read c. 1916 titled "What is a Good Newspaper" in the "New York Evening Journal." In part it read, "After news and humor come good pictures. In this day of hurry we learn through the eye, and one picture may be worth a million words." It seems to have emerged into general use via the medium of advertising (which scaled down the number and also gave the expression its spurious origin story as "a Japanese proverb" or some such thing, by 1919). Earlier various acts or deeds (and in one case "the arrow") were said to be worth a thousand words.
