How can I view all WP generated thumbnails in Media Manager?

2 Views

When WP creates thumbnails from the original uploaded image, they are hidden from view inside the Media Manager listing. Can they be made visible, via some filter or action so that you can selectively edit/delete them?

  1. Notice:

    I’m considering that by Media Manager you’re referring to the Media Library. 

    /wp-admin/media.php

    Maybe pre_get_posts could handle this, but won’t get there…

    I’d propose an alternative solution that prevents seeing lots of duplicates in the Media Library page:

    enter image description here

    The output of the All Thumbs column is simply a link to the image.
    But I think it can be easily adapted to include at least a delete capability, using some PHP script.

    It could also be coupled with jQuery behavior control and CSS styling…

    if( is_admin() )
{
    add_filter( 'manage_upload_columns', 'wpse_7757_all_thumbs_column_register' );
    add_action( 'manage_media_custom_column', 'wpse_7757_all_thumbs_columns_display', 10, 2 );
}

function wpse_7757_all_thumbs_column_register( $columns ) 
{
    $columns['all_thumbs'] = 'All Thumbs';

    return $columns;
}

function wpse_7757_all_thumbs_columns_display( $column_name, $post_id ) 
{
    if( 'all_thumbs' != $column_name || !wp_attachment_is_image($post_id) )
        return;

    $full_size = wp_get_attachment_image_src( $post_id, 'full' );
    echo '<div style="clear:both">FULL SIZE : '.$full_size[1].' x '.$full_size[2].'</div>';

    $size_names = get_intermediate_image_sizes();

    foreach( $size_names as $name )
    {
        // CHECK THIS: http://wordpress.org/support/topic/wp_get_attachment_image_src-problem
        $the_list = wp_get_attachment_image_src( $post_id, $name );

        if ( $the_list[3] )
            echo '<div style="clear:both"><a href="'.$the_list[0].'" target="_blank">'.$name.'</a> : '.$the_list[1].' x '.$the_list[2].'</div>';
    }
}
