Text Wrap Around Image in Post

[Patrice]

I had made some changes to my theme (http://leadthewayout.com), and now I'm not able to text wrap an image within a post or page. It had worked before, but now it is not. The changes I had made included changing all of the width/height sizes to 0 in the Media section so that Wordpress doesn't automatically create extra image files, and i added the following to my CSS file to align images that were hard coded on page templates.

.alignright  {
   float: right;
   }

.alignleft {
   float: left;
   }

And I change my float to none in the following code which allowed me to center images above the text, but now I'm not able to wrap it.

#contentleft p img {
	border: none;
        float: none;
	margin: 10px 10px 10px 10px;
	}

Any help would be great. Thanks.
