スライダーを作成しましたが、ロジックのどこかが間違っています。すべての画像を表示することはできますが、順番に表示することはできません。したがって、最初はそのimage2の後にimage1..シーケンスが私のロジックで間違っています。ブラウザに入ると画像が読み込まれますが、読み込みに時間がかかりました。

ライブデモのリンクは次のとおりです。

このhttp://codebins.com/bin/4ldqp9c/23 ?

      if  ( prevIndex < maximages ){
       shuffleIndex = prevIndex;
       prevIndex++; 
      }
      else {
        prevIndex=0;
        shuffleIndex=prevIndex;
        prevIndex++;
      }
