   Keterangan :
   Kode script warna merah (paling atas) adalah kode script jQuery.min.js  yang saya gunakan untuk membuat slider ini. Jika pada template Anda sudah terdapat jQuery.min.js, walaupun serinya berbeda, kode warna merah diatas tidak perlu lagi Anda masukkan. Cukup satujQuery.min.js yang ada di template, terserah mau seri berapa, kalau bisa versi yang terbaru.
   Angka 5 yang berwarna Ungu : Jumlah post yang ditampilkan dalam slider
   Angka 407 dan 240 yang berwarna hijau : Panjang dan lebar image besar
   Angka 75 dan 50 yang berwarna kuning : Panjang dan lebar image kecil
6. Kemudian cari kode <div id='main-wrapper'> kemudian letakkan kode berikut dibawahnya : 
<b:if cond='data:blog.url == data:blog.homepageUrl'>
<div id='slide-wrapper'>
<b:section class='slide' id='slide' preferred='yes'/>
</div>
 </b:if> 
7. Setelah langkah diatas, save templates. Kemudian klicklayout >> add gadget yang berada di atas posting blog masukkan kode ini pada kotak HTML/Javascript :    
<div id='featuredContent'>
<div class='sliderwrapper' id='featured-slider'>
<script>
document.write("<script src=\"/feeds/posts/default?max-results="+numposts3+"&orderby=published&alt=json-in-script&callback=showrecentposts3\"><\/script>");
</script>
</div>
<div id='paginate-featured-slider'>
<ul>
<script>
document.write("<script src=\"/feeds/posts/default?max-results="+numposts3+"&orderby=published&alt=json-in-script&callback=showrecentposts4\"><\/script>");
</script>
</ul>
<div class='clear'></div>
</div>
<script type='text/javascript'>
featuredcontentslider.init({
id: "featured-slider", //id of main slider DIV
contentsource: ["inline", ""], //Valid values: ["inline", ""] or ["ajax", "path_to_file"]
toc: "markup", //Valid values: "#increment", "markup", ["label1", "label2", etc]
nextprev: ["", ""], //labels for "prev" and "next" links. Set to "" to hide.
revealtype: "mouseover", //Behavior of pagination links to reveal the slides: "click" or "mouseover"
enablefade: [true, 0.4], //[true/false, fadedegree]
autorotate: [true, 5000], //[true/false, pausetime]
onChange: function(previndex, curindex){ //event handler fired whenever script changes slide
//previndex holds index of last slide viewed b4 current (1=1st slide, 2nd=2nd etc)
//curindex holds index of currently shown slide (1=1st slide, 2nd=2nd etc)
}
})
</script>
</div>
