How do I transfer a HTML "value" ?

How do I transfer the value from this line:(value="40%")

<form name="per" method="document">
<input name="percent" type="radio" value="40%">40%

to this line:(height="40%")

<img src="lon 004.jpg" getimagesize("lon 004.jpg");width="40%" height="40%" alt="004">

I want to give the "image height the value from the radio button selected. This will allow the image to be resized on my page by the selected value. I don't want to open a new window, I actually want to resize several images at the sane time.

Maybe there is a script that will do this for me?

Thanks Lon

for(var i=0; i<document.formname.radioname.length; i++) {
if(document.formname.radioname[i].checked==true) {
document.getElementById(imageID).setAttribute("height", document.formname.radioname[i].value);
}
}
