Until today, I did not know that an image does not need to be a picture:
From the Oxford dictionary:
Image: [countable] a picture, photograph or statue that represents somebody/something
Reading a story titled "The Bronze Image", they talk of a small bronze image of the God Ganesha. From the context (and also because it is bronze) it is clear that it is not a picture. However, why did the author not use "a statue" then, or "a figure"? Is there anything special about using "image" in this sense?
