I was looking at the source of an email. A newsletter to be precise, and came upon "xidth= and xeight=". I've never seen these before nor could I find anything on the web. I tried changing them to width & height and it did change the layout. I found them in a table layout as follows (truncated):
><td colspan="3" bgcolor="#FFFFFF">
<font face="verdana,arial,helvetica" size="-1" color="#5975C8">
<img src="http:##www.somesite.com/newsbanner.jpg" alt="banner" xidth="600" xeight="60" border="0"><br>
Just curious.
