1.   Rancangan -> Tambah Gadget
      Pilih HTML/JavaScript.

2.   Masukkan dalam kontennya
      kode yang ada di bawah ini :

<div id="outerContainer">

<div id="imageScroller">
<div id="viewer" class="js-disabled">
<a class="wrapper" href="URL Link 1 Anda" title="........"><img class="logo" id="........" src="URL Gambar 1 Anda" alt="........"></a>
<a class="wrapper" href="URL Link 2 Anda" title="........"><img class="logo" id="........" src="URL Gambar 2 Anda" alt="........"></a>
<a class="wrapper" href="URL Link 3 Anda" title="........"><img class="logo" id="........" src="URL Gambar 3 Anda" alt="........"></a>
<a class="wrapper" href="URL Link 4 Anda" title="........"><img class="logo" id="........" src="URL Gambar 4 Anda" alt="........"></a>
<a class="wrapper" href="URL Link 5 Anda" title="........"><img class="logo" id="........" src="URL Gambar 5 Anda" alt="........"></a>
</div>
</div>
