On mouseover text to show corresponding image?

On mouseover text to show corresponding image?

Whilst I have gain more confidence over time using jQuery, I wish for some help with something I wish to create.
I wish to show a div image area and below it, just simple text. I want to however, when onmouseover the text, a corresponding image appears in the div. So for example, the text might be "Book", the image will show a book or "PC", it will show an image of a PC.

How might I be able to do this?
