This is the code for one way I tried
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>New Page 1</title>
</head>
<body>
<p>
<img border="0" src="file://C:\Program Files\Common Files\Microsoft
Shared\Stationery\EmailBanner3.jpg" style="float: left"
width="426" height="80" >
</p>
</body>
</html>
This is the code for the other way
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML xmlns

= "urn:schemas-microsoft-com

ffice

ffice"><HEAD>
<META http-equiv=Content-Type content="text/html; charset=windows-1252">
<META content="MSHTML 5.50.4807.2300" name=GENERATOR>
<STYLE>BODY {
BACKGROUND-POSITION: left top; MARGIN-TOP: 140px; FONT-SIZE: 10pt;
MARGIN-LEFT: 20px; COLOR: #B73C35; BACKGROUND-REPEAT: no-repeat; FONT-FAMILY:
Arial
}
</STYLE>
</HEAD>
<BODY
background="file://C:\Program Files\Common Files\Microsoft

<DIV> </DIV></BODY></HTML>
The first one puts the logo down at the bottom below the autosignature - the
second one repeats the banner across the whole email.
