Thanks again for your helpful ideas.

I ended up with a different solution than I started with.  The form 
used to have a 'view picture' button which fired a javascript function 
to open a new window with the 'file://' url of the local file to 
display.  IE was throwing 'access denied' errors on the open window 
call.

The form now has a img thumbnail for each input="file" element the a 
src of "file://".  IE will let me change the src of the img to a local 
file without throwing an error presumably because the protocols match.  
I wonder how long it will be before this loophole is closed :)  BTW, it 
works in IE6/win, Moz, and Safari.

--------  html  --------------
<input type="file" name="pic1"  size="35"
	onchange="showLocalPic(1, this.value)" />
<img src="file://" height="96" id="preview1" class="invisible" />

-------   javascript ---------
function showLocalPic(i, path2Pic) {
	if (path2Pic > '') {
/*  --- code that was failing   ---------
		winStats='toolbar=no,location=no,directories=no,';
		winStats+='scrollbars=yes,resizable=yes,width=610,height=360';
		floater=window.open('file://' + path2Pic, 'Preview', winStats);
		floater.focus();
*/
		var pic = document.getElementById("preview" + i);
		if (pic) {
			pic.src = 'file://' + path2Pic;
			pic.className = "";
		}
	} else {
		alert('Please select a picture first');
	}
}

I hope this is helpful to someone else...
