I installed the plugin and I was trying to use the thumbnail display function, I noticed the html output is wrong when a post has a featured image set.
this is how it looks when a post doest' have any featured image, the thumbnails displays the default default.png
<a title="My post without featured image" href="http://www.mydomain.com/articles/no-featured-image/" class="yarpp-thumbnail"> <span class="yarpp-thumbnail-default"><img src="http://www.mydomain.com/wp-content/plugins/yet-another-related-posts-plugin/default.png"></span> <span class="yarpp-thumbnail-title">My post without featured image</span> </a>
and this is when a featured image is assigned to a post.
<a title="This post has a featured image" href="http://www.mydomain.com/articles/has-featured-image/" class="yarpp-thumbnail"></a> <a title="This post has a featured image" href="http://www.mydomain.com/articles/has-featured-image/"><img width="120" height="120" alt="wine cork art tray" class="attachment-yarpp-thumbnail wp-post-image" src="http://www.mydomain.com/wp-content/uploads/2013/08/wine-cork-art-tray-120x120.jpg"></a> <span class="yarpp-thumbnail-title">This post has a featured image</span>
I also tried other YARPP templates but the same thing happens.
So basically the Related posts are displayed all over the place instead of being neatly align, this is not a css problem.
Here's a screenshot to show what's going on, left featured images, right none
