The use of comment tags such as <!--bgsound src="http://www.wtv-zone.com/bluefox/midis/dion.mid"--> or
you can place the URL in your signature but always use relative URL's vice absolute URL's when creating an embedded signature whether you use a sound tag or not. The below is the same as above using a relative URL.
<!--bgsound src="midis/dion.mid" loop="2"-->
If you use a sub-directory for your signature then <!--bgsound src="../midis/dion.mid" loop="2"--> would be called for. See this page for an explanation of relative URL's.
Example of the URL to be embedded: http://www.wtv-zone.com/bluefox/key/sig101.html
For ease of changing signatures I called the above sig101 and the next signature could be sig102 then sig103 etc., etc., etc.
<html>
<body bgcolor="#171726" text="#82a9d9">
<embed
src="http://www.wtv-zone.com/bluefox/key/sig101.html">
</body>
</html>
The above body and text colors are the present default colors.
No center tags or a width attribute is used with the embed tag as all codes are programmed at your host server.
Now let's say I have a sig102, 103 & 104 etc., etc. I would use comment tags to show what the body bgcolor and text should be used with each signature.
<!--sig101 bgcolor".." text="..."-->
<!--sig102 bgcolor".." text="..."-->
<!--sig103 bgcolor".." text="..."-->
Now this way I can quickly change signatures by changing just one number and maybe the colors.
I also created a separate sub-directory for embedding and as you see in the above the sub's name is key but I really should have used the name of sig for the sub-directory per se.
The body colors are the same in the embedded URL as they are in the signature box or change the text color or both. After you change your signature send a test e-mail message to yourself and see what it looks like and if necessary make a test post here.
I had asked one of the foremost if not the foremost PageBuilder heavy hitter about signature embedding and the below was his reply.

After your sig code, use either a <noscript> or <script> tag and it will hide the junk at the bottom of the page. If you want to have a clean slate to put your signature on, then also use the AE (advanced editor) Fix to cancel out the template head & body - again, use either the <noscript> or <script> tags to do that as well:
Here is the AE Fix for PageBuilder written by Ken Dine. JaxRed has quite a few tutorials for PageBuilder which may be seen here. If you need a tutorial on how to place an image in your PageBuilder Scrapbook and extract the URL for that image try this site and BTW you cannot upload sound files to PageBuilder.

A width is not used with the embed tag nor is center .... everything single code is created in your host server and simply embedded using this <embed src="..."> command after the body tag.
Every thing such as images, sound et al is either uploaded, transloaded or beamed to your host server. No hot linking whatsoever with maybe the rare exception of one of weather bars. You say you're not sure how to transload well here's a tutorial to explain FTP aka File Transfer Protocol.
Now when it comes to using CSS and covering the sidebar or a full page e-mail or post I do not have a clue. All ideas in this regard are welcome.
If you use an image above the header those codes will still be used within your signature box.
