the code in firebug is:
<article class="post-64 post type-post status-publish format-standard category-artistas entry" itemtype="http://schema.org/BlogPosting" itemscope="itemscope">
<a class="alignleft" title="José María Moreno Rodrigo" href="http://alandalusfoundation.org/jose-maria-moreno-rodrigo/">
<img class="entry-image attachment-post" width="264" height="200" itemprop="image" alt="jose-maria-moreno-rpdrigo" src="http://alandalusfoundation.org/wp-content/uploads/2013/12/jose-maria-moreno-rpdrigo-264x200.jpg">
</a>
<header class="entry-header">
<h2 class="entry-title">
<a title="José María Moreno Rodrigo" href="http://alandalusfoundation.org/jose-maria-moreno-rodrigo/">José María Moreno Rodrigo</a>
</h2>
</header>
<div class="entry-content">
</article>______
the line: <header class="entry-header"> takes same height than the image, so the of the “entry-content” starts down the image.
