I have created CSS code for you to make your featured images show up in the corners of Blog post thumbnail feed. Just add an additional CSS code to your WordPress theme (Apperance –> Custom CSS)
/* featured image left of content on blogs page */ [class="attachment-full wp-post-image"] { height:40%; max-width:40%; float: left; margin-right:20px; padding-right: 20px; } /* featured images resized and left from content on post page */ [class="attachment- size- wp-post-image"] { height:60%; max-width:60%; float: left; margin-right:20px; padding-right: 20px; }
