putting img before text under headings in Hero example

[Angelo Chen]

Hi,
in the Bootstrap2 Hero example, it has three headings below the 'hero-
unit', I'd like to put a small image before the text under heading,
following code did add the img, but img is above the text, what i like
is:

[image] [ text ]

side by side, any hints how to achieve this? Thanks,

  <!-- Example row of columns -->
      <div class="row">
        <div class="span4">
          <h2>Heading</h2>
          <img src="https://si0.twimg.com/sticky/error_pages/
twitter_logo_header.png" />
           <p>Donec id elit non mi porta gravida at eget metus. Fusce
dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut
fermentum massa justo sit amet risus. Etiam porta sem malesuada magna
mollis euismod. Donec sed odio dui. </p>
          <p><a class="btn" href="#">View details &raquo;</a></p>
        </div>
