Need help with Smilies

Smilies could not display correctly after i chose them.
It played [[Image:]] after saving the page, but it works during the selection and modification。
It displayed nothing when select smiley and right click to view the preview
The Fckeditor version is 2.66 and mediawiki version is 1.15.3

steps:
1.select smiley tool
2. choose smiley
3. save the page

Displayed with [[Image:]]

1. select smiley tool
2. choose smiley
3. right click
4. choose preview

None information shows in the image preview

Those are the changes for FCKeditor

LocalSettings:
require_once( "extensions/FCKeditor/Fckeditor.php" );
$wgUseAjax = true;

fckeditor_config
FCKConfig.ToolbarSets['Wiki'] = [

['Source','-','Save','NewPage','-'],
['Cut','Copy','Paste','PasteText','PasteWord','-','Print'],
['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'],

] ;
