i think i did what you want on my private site:   www.wolfsbau.de
See the latest news module on the home page.

Here's what i did:
In the view settings of the latest news module, i applied a css class "HomepageNewsFeatured" to the parent element, containing  the news teaser and the image. In my case this is a table cell tag.

Then i defined the css-properties of the img tag within this td-tag in the Portal stylesheet:

td.HomepageNewsFeatured img {
float: left;
margin-right: 10px;
margin-bottom: 10px;
}
