Aesthetically, just what is 'imagery', anyway? It is, in fact, a very simple idea that is somewhat difficult to explain. In it's most basic terms, it is the act of creating images, of course, as through drawing or painting or photography, etc. Images can be direct representations of people, places , and things of course, but they can also be symbols that evoke a particular thing, such as an emotion or feeling, or a memory, or a quality. Such an image can represent a 'picture' of that thing whether or not it 'looks' exactly like that thing or not.
