why images can mean so many things

No one knows why images mean so many things, but they do and that is really cool. They can say a lot an mean so much, like the lyrics i like form the song ''never lose your flame." The title itself you can use it as a image. picturing some one holding a flame close to their hands and to their heart. this song has a lot of imagery used and they mean so many things. i think its good imagery means so many things it helps us understand and relate and not every one will see everything differently or the same.
