4) Add a thumbnail for each post
Have you ever wondered how others manage to embed a thumbnail for every single post? Well, you can simply do it by adding a custom field into your post.
In your WordPress Write section, scroll down to find 'Custom Fields'. Click on it to reveal the input fields. Under the Key, type 'thumbnail'. Under the value, type the URL of the thumbnail image that you want to embed. Click 'Add Custom Field'.
To display the thumbnail on your blog, you can query it by inserting the following line to your wp theme.
<img src="<?php echo get_post_meta($post->ID, 'thumbnail', true); ?>" alt="" width="80" height="80" />
