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 : Jumlah post yang ditampilkan dalam slider. Angka 407 dan 240 : Panjang dan lebar image besar. Angka 75 dan 50 : Panjang dan lebar image kecil
7. 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">
</b:section></div>
</b:if><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>");
