remove_action( 'admin_notices', array( Yoast_Notification_Center::get(), 'display_notifications' ) );
remove_action( 'all_admin_notices', array( Yoast_Notification_Center::get(), 'display_notifications' ) );

Oh yes please. It even overrides the WP upgrade screen.

Line 35 of admin/class-admin-init.php:
add_action( 'admin_init', array( $this, 'redirect_to_about_page' ), 15 );

but the object is loaded without reference, so I’m not sure how to trigger a remove_filter() from my own plugin.

remove_action( 'admin_init', array( ___????__, 'redirect_to_about_page' ), 15 );

+1 Can you post the fix technomad42?

Even safer is to use wp_upload_dir();

function query_images() {
    $sizes = array('thumbnail', 'medium', 'large', 'full');
    if (function_exists('get_intermediate_image_sizes')) {
      $sizes = array_merge(array('full'), get_intermediate_image_sizes());
    }
    $this->images = array();
    $upload_dir = wp_upload_dir();
    foreach ($sizes as $size) {
      list($url, $width, $height) = wp_get_attachment_image_src($this->id, $size);
      $filename = str_replace( $upload_dir['baseurl'], $upload_dir['basedir'], $url);
      if (file_exists($filename)) {
        list($measured_width, $measured_height) = getimagesize($filename);
        if ($measured_width == $width &&
            $measured_height == $height) {
          $this->images[$size] = (object) array(
            'url' => $url,
            'width' => $width,
            'height' => $height
          );
        }
      }
    }
  }
