I'm trying to show thumbnails before the excerpts but I can't get it to work. I'm not sure I understand how it works. I read other posts about this but it didn't help me.
In Configure Excerpts, I have selected Only Excerpts everywhere.
In the Post Thumbnails section, I have set Thumbnails Width and Height to 150 and Crop to No. Post Thumbnail CSS is set to the default:
margin: 0 10px 5px 0;
In Post Thumbnails / Post Thumbnail CSS, it says:
Style the Post Thumbnail. It is placed inside the 'bodycopy' of a post, right before the first paragraph of the excerpt:
<img POST THUMBNAIL HERE class='wp-post-image' />
<p>Post Excerpt starts here...</p>
Thanks for your help
