私の次の結婚式のウェブサイト（www.hilaryandmatthew.com）には、本当に気の利いたJQueryスライドショーがあります（www.dynamicdrive.comの提供）
できるだけ早く助けが得られることを願っています。招待状を送信する前に、自分のサイトをシャープに見せたいと思っています。jQueryについては何も知りません。したがって、私はオープンソースコードをコピーして貼り付けるという落とし穴を経験します。
IE8でページを読み込もうとすると、次のエラーが発生します。
メッセージ：'imagearray [...]。0'がnullであるか、オブジェクトではありません行：39文字：3コード：0 URI：http ://www.hilaryandmatthew.com/includes/slideshow/fadeslideshow.js
これは、関数'fadeSlideShow（settingarg）'に渡される画像配列のコードです。

別の.jsファイルにエラーがあるコードは次のとおりです。
