Pro Tip: Master the new “Post Thumbnail” feature in WordPress 2.9

Before the release of WordPress 2.9, setting up “post-image” support for your blog was a more tedious task than it needed to be. Fortunately, this is no longer an issue. I'll show you how to set it up in this four-minute video quick tip.

Step 1: Edit the 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 image tag into loop

In the "if have_posts()" loop, just place this code wherever you like. At this point, WordPress will insert the image tag on the page accordingly. Note that you will have access to the "wp-post-image" class, which you can then use to format/style the image.

<?php the_post_thumbnail(); ?>
