How to show full featured image in wordPress single post

Display featured image in WordPress post as full, large, medium, thumbnail size Every available WordPress theme doesn’t give you the option to control if you want to show featured image in a post or in what size you want to display them.The image is crucial for your blog post as it’s probably first thing audience notice.For ex, I am using Hueman theme and that doesn’t display featured image in single post. Here is what I did and thought to share so you can be benefited. 

  • Go to your theme directory
  • For ex: wp-content/themes/hueman
  • Take a backup of single.php
  • Edit single.php and search for <?php the_content(); ?>
  • Add following above the <?php the_content(); ?>
<?php
if ( has_post_thumbnail() ) { // check if the post has a Post Thumbnail assigned to it.
the_post_thumbnail( 'full' );
}
?>
  • Save the file and refresh your wordpress to see them in action.

Above code will show featured image in the single post as original image size. This is how single.php will look like.

If you want to control the size, you can change the_post_thumbnail parameter.

To display default thumbnail size (default 150px x 150px max)

the_post_thumbnail();

To display in medium size (default 300px x 300px max)

the_post_thumbnail( 'medium' );

To display in large size (default 640px x 640px max)

the_post_thumbnail( 'large' );

To display in original uploadedsize

the_post_thumbnail( 'full' );
