Obtaining <TD> cell width in a javascript when using "%" of screen option

Copy linkTweet thisAlerts:
Dec 29.2002

I have looked through the JavaScript Goodies book and have found how to reference the size of a <IMG> tag. I want to grab the width/height of a percentage defined table/cell and then take that value to define the picture length. I am trying to have the images resize when the browser/table resizes. But, I am having difficulty obtaining the actual value that is assigned. I have named the cell and used document.cellname to try to reference it to no avail. Any suggestions?

Thanks,
Ken
