JQuery Efek Nivo Slider Tanpa Plugin

Untuk menciptakan slideshow dengan efek seperti Nivo Slider. Slideshow ini menggunakan konsep yang mirip dengan Nivo Slider, yaitu mengambil URL gambar untuk dijadikan sebagai latar slice:

HTML

<figure id="slider">
    <div class="container">
        <img src="img/slide-1.jpg" alt="Deskripsi slide 1">
        <img src="img/slide-2.jpg" alt="Deskripsi slide 2">
        <img src="img/slide-3.jpg" alt="Deskripsi slide 3">
        <img src="img/slide-4.jpg" alt="Deskripsi slide 4">
    </div>
    <figcaption></figcaption>
    <nav id="slider-nav"></nav>
</figure>
