clipped from markjaquith.wordpress.com Mark on WordPress New in WordPress 2.9: Post Thumbnail Images First, in the theme’s functions.php, declare that your theme supports this feature. This will enable the UI in the WP Admin. 1 add_theme_support( 'post-thumbnails' ); That will enable Post Thumbnail UI for both Post and Page content types. If you’d only like to add it to one, you can do it like this: view source print? 1 add_theme_support( 'post-thumbnails', array( 'post' ) ); // Add it for posts 2 add_theme_support( 'post-thumbnails', array( 'page' ) ); // Add it for pages Simply remove the one you don’t want to support. view source print? 1 set_post_thumbnail_size( 50, 50 ); // 50 pixels wide by 50 pixels tall, box resize mode view source print? 1 set_post_thumbnail_size( 50, 50, true ); // 50 pixels wide by 50 pixels tall, hard crop mode view source print? 1 <?php 2 if ( has_post_thumbnail() ) { 3     // the current post has a thumbnail 4 } else { 5     // the current post lacks a thumbnail 6 } 7 ?>
