Here's another example, by using a default template module "About me".
Just by adding a 1x1 table around the picture of moofito, it does the same. The module still has " clear" as module class suffix. (I'll put up screen shot of with and without " clear" for you to see the difference. You can test this on your demo site, does it on fresh install.
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td><img src="images/stories/demo/portrait.png" alt="About me" title="About me..." style="float: left; border: 0pt none; margin-right: 20px;" align="left" border="0" /></td>
</tr>
</table>
<div class="about_me">
