2. Ya ubicado este codigo pegamos arriba de este lo siguiente

<!-- Articulos relacionados con miniaturas -->
<b:if cond='data:blog.pageType == &quot;item&quot;'>
<style type='text/css'>

#related-posts {
float:center;
text-transform:none;

3.  Luego buscamos este codigo

<div class='post-footer-line post-footer-line-1'>

4. Abajo de el codigo anterior pegamos lo siguiente

<!-- Articulos relacionados con miniaturas -->

<b:if cond='data:blog.pageType == &quot;item&quot;'>
<div id='related-posts'>
<b:loop values='data:post.labels' var='label'>
<b:if cond='data:label.isLast != &quot;true&quot;'>
</b:if>
<b:if cond='data:blog.pageType == &quot;item&quot;'>
<script expr:src='&quot;/feeds/posts/default/-/&quot; + data:label.name + &quot;?alt=json-in-script&amp;callback=related_results_labels_thumbs&amp;max-results=6&quot;' type='text/javascript'/></b:if></b:loop>
<script type='text/javascript'>
var currentposturl=&quot;<data:post.url/>&quot;;
var maxresults=4;
var relatedpoststitle=&quot;Post relacionados&quot;;
removeRelatedDuplicates_thumbs();
printRelatedLabels_thumbs();
</script>
</div><div style='clear:both'/>
</b:if>

<!-- Articulos relacionados con miniaturas -->

Por defecto el script solo te mostrara 4 entradas pero si quieres cambiarle el numero de entradas entonces al codigo var maxresults=4; le cambias el 4 por el numero que quieras ponerle.
