You can put a custom HTML module, or e.g. a 3rd party slideshow module into the position-8 module position. But if you would like a similar arrangement of an image, text, and a button as above, you can use the following code in a Custom HTML module:

<div class="media">
  <a class="pull-left" href="#"> 
    <img src="/joomla-templates/tiger3r-free/images/search.png" alt="" /> 
  <div class="media-body">
    <h2 class="media-heading">Your title</h2>
    Your text is here.... <br /> 
    <a class="btn btn-inverse" style="margin-top: 10px;" href="#">Link Button</a>
