[thelist] Looking for Mr. JavaScript

[Sam Carter]

I need a JavaScript that will emulate the function of the browser's back
button on
 
<img src="backbutton.gif" onclick="myscript">
 
with this caveat:
 
If JavaScript is disabled, I need to *NOT* render the <img>, instead -
render text that reads "Use your browser's back button to return".
 
<noscript> should take care of the latter, but I'm not sure how I can omit
rendering of the <img onclick="myscript"> if JS is disabled?  After all, JS
will be disabled, so it isn't a tool that can omit rendering.
 
Any ideas? CSS display:none when JavaScript is disabled?  Any way to do
that?
