(A Picture Speaks a Thousand Words)
Yes i agree with the idiom, because it's true that a single picture can show many information to us. The meaning of this idiom is a single picture can tell us many information and each people have a different view of picture.
Even the picture look's ugly it have it's own meaning if we try to understand it. Also picture can give us an idea, and helps us to make something interesting. Picture are also helps us to remember our past, joy, and sadness.
But now a day many young people abuse the art of the picture. This is causing gossip occurs. Usually the victims of this gossip is our artist's. So we should use this art properly, so that no more gossip victims.
For my conclusion a picture can be describe in to many things. So when you see a picture you must carefully describe it, so that bad things can be prevent. For my advice, do not judge if you don't know how to describe the meaning of the picture, and use this art properly.
