Quick Tip: How to Use the New “Post-Thumbnail” Feature in WordPress 2.9

Thursday, 04 February 2010 00:58

Up until the release of WordPress 2.9, setting up “post-image” support for your blog was a bit more tedious a task than it really needed to be. Luckily, that’s no longer an issue. I’ll show you how to get setup in this four minute video quick tip.

Step 1. Edit your Functions.php Page

// Enable support for post-thumbnails

add_theme_support('post-thumbnails');

// If we want to ensure that we only call this function if
// the user is working with WP 2.9 or higher,
// let's instead make sure that the function exists first

if ( function_exists('add_theme_support') ) {
	add_theme_support('post-thumbnails');
}

Step 2. Insert the Image Tag into your Loop

Within the “if have_posts()” loop, simply place this piece of code anywhere you like. At that point, WordPress will insert an image tag onto the page accordingly. Please note that you’ll have access to a “wp-post-image” class that you may then work with to format/style the image.

<?php the_post_thumbnail(); ?>
