I shamelessly reused and modified a UDF posted here to create a change password dialog in IE. I wanted a simple informational window to tell the user where they logged in, but messagebox() wasn't cutting it because sometimes a mystery app would steal focus and cause the box to never time out. So, I stripped out the forms and put what was left in my script. Everything works except a company logo I placed inline. If I run the script locally, it's okay, but when I run it on logon the image doesn't appear. This happens no matter how I address it:

http://our.intra.net/logon-banner.gif
@ldrive\logon-banner.gif
%systemroot%\logon-banner.gif (after copying to local drive)

Is there some sort of security problem I need to address here?

code:
	DIM $title, $top, $left, $height, $Width, $False, $true
	DIM $status, $doc, $nul, $html

	$top      = "320"
	$left     = "200"
	$height   = "120"
	$width    = "300"
	$false    = 0
	$true     = -1
	$title = "Welcome, $fullname."
	$msg = "You have logged onto $domain, $site."
	$html= '<html>
		<head>
		<title>$title</title>
	<style>
	<!--body{ background-color: mediumblue; color: white;font-family: baskerville old face, arial;

	<body scroll=no onresize="window.resizeto(300,120);" >
