Hi
You will need to add a new article in the Students Highlight category using this code
<p><img class="img-border" title="Sample image" src="images/sampledata/ja_university/sam-18.jpg" alt="Sample image" align="left" /></p>
<div class="student-info">
<ul class="info">
<li><strong>+ Dept:</strong> Math</li>
<li><strong>+ Age: </strong> 24</li>
<li><strong>+ Sex: </strong> Female</li>
</ul>
<ul class="social-links">
<li class="facebook"><a title="Facebook" href="#">Facebook</a></li>
<li class="twitter"><a title="Twitter" href="#">Twitter</a></li>
<li class="email"><a title="Email" href="#">Email</a></li>
</ul>
</div>
<hr id="system-readmore" />
