Hi! Sorry to bother you again, but css is still not identical and when looking at the source, there does seem a image class missing:
<li>
<div class="author_left" style="width:50px;height:50px;">
<a href="https://domain.com/">
<img width="50" height="50" src="https://domain.com/wp-content/uploads/2014/06/image.jpg" class="attachment-50x50 wp-post-image" alt="image name" /> </a>
</div>
<div class="author_right">
<a href="https://domain.com/">
Title </a>
<br /><span class="post-date"><small>30.6.2014</small></span>
</div>
</li>
<li>
<div class="author_left" style="width:50px;height:50px;">
<a href="https://domain.com/">
<img src="https://domain.com/wp-content/uploads/2014/06/no-image.png" width="50" height="50" />
</a>
</div>
<div class="author_right">
<a href="https://domain.com/">
Title </a>
<br /><span class="post-date"><small>30.6.2014</small></span>
</div>
</li>
