Here is what you would see in Notepad for an uncomplicated post:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META content="text/html; charset=iso-8859-1" http-equiv=Content-Type>
<STYLE></STYLE>

<META content="MSHTML 5.00.2614.3401" name=GENERATOR></HEAD>
<BODY background=cid:040101beaca6$04f890a0$ae4294ce@bnovak>

<BGSOUND src="cid:040201beaca6$04f890a0$ae4294ce@bnovak" balance=0 loop=-1 volume=0>
</BODY></HTML>
Outlook Express references the embedded files,usually between quotation marks and starting with cid.
Replace the cid references for the background file and the sound file with the paths to the files you saved, including the file names and the quotation marks:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META content="text/html; charset=iso-8859-1" http-equiv=Content-Type>

<META content="MSHTML 5.00.2614.3401" name=GENERATOR></HEAD>
<BODY background="C:\windows\Desktop\image.jpg">
<BGSOUND src="C:\windows\Desktop\sound.mid" balance=0 loop=-1 volume=0>
</BODY></HTML>
Nowsave the notepad file and name it with a htm extension, such as: Stationery.htm
