mouseover question

[slechols]

I am somewhat familiar with image swapping and mouseover, but I don't think this will solve my problem. Can I mouseover some text or a button and have an image display elsewhere on the screen, such as in a table cell?

<a onMouseover="document.Images.someimage.src='swap.gif'" onMouseout="document.Images.someimage.src='unswap.gif'>sometext</a>

<img src="unswap.gif" name="someimage">
