Since it is a JavaScript usage then your readers need to enable JavaScript scripting language of their browser. And I’m sure 98.99% of them enable this setting. So don’t worry about it.

Banners will be displayed randomly each time browser reloads. It means every page view will have its own banner view. And it depends on how many banners you have. You may refresh this page (press F5) to see how it works. Image banner above will change to another banner.

Now it’s time to grab the code. You have to insert code below to your Blogger template. Please make a copy backup of your template.

<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
  var jumlah_iklan = 3;
  var waktu_sekarang = new Date()
  var detik = waktu_sekarang.getSeconds()
  var pasang_iklan = detik % jumlah_iklan;
  pasang_iklan +=1;
  if (pasang_iklan==1) {
  txt="Write Title";
  url="Destination URL";
  alt="Name of URL";
  banner="URL of banner image";
  width="468";
  height="60";
  }
  if (pasang_iklan==2) {
  txt="Write Title";
  url="Destination URL";
  alt="Name of URL";
  banner="URL of banner image";
  width="468";
  height="60";
  }
  if (pasang_iklan==3) {
  txt="Write Title";
  url="Destination URL";
  alt="Name of URL";
  banner="URL of banner image ";
  width="468";
  height="60";
  }
  document.write('<center>');
  document.write('<a href=\"' + url + '\" target=\"_top\">');
  document.write('<img src=\"' + banner + '\" width=')
  document.write(width + ' height=' + height + ' ');
  document.write('alt=\"' + alt + '\" border=0><br>');
  document.write('<small>' + txt + '</small></a>');
  document.write('</center>');
  // End -->
</SCRIPT>

And here it is some guidance about customizing the code with your own settings. Code above will display three banners in queue. If you want to add another banner then please var jumlah_iklan = 3 into number of your banners amount. Then add another value to the code with the number of next banner. For an example I want to add one more banner than its default value, it is three. Then I need to add this code.

if (pasang_iklan==4) {
  txt="Write Title";
  url="Destination URL";
  alt="Name of URL";
  banner="URL of banner image";
  width="468";
  height="60";
  }

Isn’t it really easy? If you ask about how to place those codes inside Blogger template then please be patient. Basically it is just like inserting socialize widget into Blogger styled template.
