This code will keep all images people post into your comments at a specific width so they don't skew your page layout all to hell
Code:
<style type="text/css">
td.text td.text table table table td a img {width:100px;}
td.text td.text table table table td div img {width:80px;}
td.text td.text table table td img {width:260px; max-width:260px; width:auto;}
td.text td.text table table td div img {width:80px;}
* html td.text td.text table table td img {width:260px;}
* html td.text td.text table table td a img {width:90px;}
* html td.text td.text table table td div img {width:80px;}
</style>

that was one of my biggest pet peaves, people putting images in my comments that were twice the size of my layout....now this code resizes all the images so my layout stays in tact
