w.r.t the issue support for phploader it will be great if yui admin settings can also include the version support by including the following in yui_admin() function of yui.module

	$form['yui_version'] = array(
    '#type' => 'textfield',
    '#title' => t('Version of YUI'),
    '#description' => t('Version of YUI to use. If you do not know leave the default value.'),
    '#default_value' => variable_get('yui_version','2.8.0r4'),
   	'#required' => TRUE,
	);
