PHP Deprecated create_function()

happens with PHP 7.2

PHP Deprecated: Function create_function() is deprecated in /path/wp-content/plugins/ajax-thumbnail-rebuild/ajax-thumbnail-rebuild.php on line 297

you can easily fix it by replacing line 297

add_action( 'plugins_loaded', create_function( '', 'global $AjaxThumbnailRebuild; $AjaxThumbnailRebuild = new AjaxThumbnailRebuild();' ) );

with

function ajax_thumbnail_rebuild_init() {
  global $AjaxThumbnailRebuild;
  $AjaxThumbnailRebuild = new AjaxThumbnailRebuild();
}
add_action( 'plugins_loaded', 'ajax_thumbnail_rebuild_init' );

why did you use a create function for that anyway?
