WordPress 3.5: Switch back to Old Media Uploader?

Question

Is there any way to switch back to the old media uploader in WordPress 3.5? The new one is very slow for me, as I have thousands and thousands of images across my site, and I have a few plugins that only work with the old uploader.

Answer 1

I just found this gem in WordPress forums, all props to A.Morita.

Is there a way to disable the new Media Manager?

Summing up all the code published, this is it:

/**

 */

/**
 * Old upload Thickbox
 */
add_action( 'admin_head', 'remove_media_buttons' );

function remove_media_buttons()
{
    remove_action( 'media_buttons', 'media_buttons' );
    add_action( 'media_buttons', 'old_media_buttons' );
}

function old_media_buttons( $editor_id = 'content' ) 
{
    $context = apply_filters( 'media_buttons_context', __('Upload/Insert %s') );
    
    $img = '<img src="' 
        . esc_url( admin_url( 'images/media-button.png?ver=20111005' ) ) 
        . '" width="15" height="15" />';
        
    echo '<a href="' 
        . esc_url( get_upload_iframe_src() ) 
        . '" class="thickbox add_media" id="' 
        . esc_attr( $editor_id ) 
        . '-add_media" title="' 
        . esc_attr__( 'Add Media' ) 
        . '" onclick="return false;">' 
        . sprintf( $context, $img ) 
        . '</a>';
}

/**
 * Featured image
 */
add_action( 'wp_default_scripts', 'unset_media_views', 999, 1 );
add_action( 'admin_head', 'remove_wp_print_media_templates' );

function unset_media_views($scripts)
{
    unset( $scripts->registered['media-views'] );
}
    
function remove_wp_print_media_templates()
{
    remove_action( 'admin_footer', 'wp_print_media_templates' );
    remove_action( 'wp_footer', 'wp_print_media_templates' );
}


/**
 * Adjust Full Screen behavior
 */
add_action( 'after_wp_tiny_mce', 'fullscreen_media_button' );

function fullscreen_media_button()
{
    ?>
    <script type="text/javascript">
    fullscreen.medialib = function() 
    {
        var href = jQuery('div#wp-content-media-buttons a.thickbox').attr('href') || '';
        tb_show('', href);
    }
    </script>
    <?php
}
