WordPress Thumbnails Outside The Loop
Occasionally you’ll need to fetch a posts image outside of the loop.
<?php $thumb = get_post_meta($post->ID,'_thumbnail_id',false); $thumb = wp_get_attachment_image_src($thumb[0], false); $thumb = $thumb[0];?> <img src="<?php echo $thumb; ?>" alt="" />
Combine this with the Timthumb script for control over image size. IE:
<?php $thumb = get_post_meta($post->ID,'_thumbnail_id',false); $thumb = wp_get_attachment_image_src($thumb[0], false); $thumb = $thumb[0]; if ( has_post_thumbnail() ) { ?> <img src="<?php bloginfo('template_directory'); ?>/timthumb.php?src=<?php echo $thumb; ?>&w=150&h=150&zc=1" alt="<?php the_title(); ?>" width="150" height="150" /> <?php } ?>
Not Recommended, But Available Option
This will output the URL to an image with the size predefined by ‘post-thumbnail’ in your functions file when registering the functionality for post images.
<?php $thumb = get_post_meta($post->ID,'_thumbnail_id',false); $thumb = wp_get_attachment_image_src($thumb[0], 'my-custom-size', false); $thumb = $thumb[0]; echo $thumb; ?>
The above code is referencing ‘my-custom-size’, which we can see below as being 405×180. Typically it is not advised to use these predefined sizes as it will overload your uploads directory with additional sizes, and it puts strain on your server when uploading images. Better to use the above method with the Timthumb script to get an exact image size, while making use of image caching.
if ( function_exists( 'add_theme_support' ) ) { // Added in 2.9 add_theme_support( 'post-thumbnails' ); set_post_thumbnail_size( 50, 50, true ); // Normal post thumbnails add_image_size( 'my-custom-size', 405, 180, true ); }
