Membuat Gambar Berjalan Dengan jQuery


Preview dari tutorial ini adalah seperti ini :



Agar Anda bisa lebih jelas lagi, lihatlah DEMO-nya di sini.

Untuk membuat seperti yang demikian, berikut ini tutorialnya :


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>

</div>
<script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
