Add thumbnail feature in WordPress theme:

In latest theme almost every theme support thumbnail you can read WordPress Codex or just open up your theme’s functions.php file in your favorite editor or create it if there’s no such file in your theme folder. Add this little code snippet to this file:


For backwards compatibility you should wrap this inside a function check for the new add_theme_support:

if ( function_exists('add_theme_support' ) )

This makes sure WordPress installation prior to 2.9 won’t get screwed up when using a theme with this new feature.After you’ve added the above mentioned code into your functions.php file there should be a new Post Thumbnail box in the WordPress editor view on the right side we already discuss above.

Display The Post Thumbnail in Your Theme

Basically all you have to do is to add this new template tag in your theme files where you want to display the post thumbnail, most certainly in your index.php file

<?php the_post_thumbnail(); ?>

This template tag will display the thumbnail sized post thumbnail by default and is essentially the same as:

<?php the_post_thumbnail('thumbnail'); ?>

But of course you can grab the other sizes WordPress automatically creates when you upload an image:

<?php the_post_thumbnail('medium'); ?>

<?php the_post_thumbnail('large'); ?>

The code will output a generic <img /> tag with a class of wp-post-image.

Customize you Output: If you want to adjust the generated output of the <img /> tag you can do this by using some array stuff. So let’s say you want to have the post thumbnails to be 200x200px big and another class assigned to it, you can extend the template tag like so

<?php the_post_thumbnail(array( 200,200 ), array( 'class' => 'alignleft' )); ?>

If you want to add more than one class you can do this like so

<?php the_post_thumbnail('medium', array('class' => 'alignleft another_class')); ?>

And you can add any attributes to the <img /> tag like a title, rel or an alt attribute. For accessibility reasons you should always add at least the alt-attribute

<?php the_post_thumbnail('medium', array('class' => 'alignleft', 'alt' => 'alttext')); ?>
