replace form element with image?

[49er]

I have a form that contains 2 checkboxes and a radion button. What I would like to do is if the user checks the first checkbox then the 2nd checkbox appears "greyed out." The greyed out checkbox is a .gif image that I created. Does anybody have any suggestions on how to accomplish this? Is there a better way of going about this? Thanks for any help.

in IE and NS6 you can use:

checkboxid.disabled=true;

otherwise, for NS4.X, you would have to have it inside a layer, and then use document.layers.layername.document.write("newcontent&quot jared@aauser.com
