เอาโค๊ดเดิมจาก http://javascript.internet.com และโค๊ดเพิ่มเติมจาก http://www.brainerror.net/scripts_js_blendtrans.php

หลักการคือใช้ฟังก์ชั่น setTimeout เหมือนเดิมในการกำหนดค่า opacity ของภาพ แล้วค่อย ๆ เพิ่มตามเวลาที่เรากำหนด

โค๊ดมีดังนี้

//change the opacity for different browsers

  var imageId = 'imggalid';
  var image = document.getElementById(imageId);
  // set speed of fading
  var speed = Math.round(2500 / 100);

  // set background to old image
  document[place].backgroundImage=document[place].src;
  
  // make new image
  var new_image = getNextImage();
  document[place].src = new_image;
  
  // set opac to 0
  changeOpac(0, imageId);

  // fade image from 0 to 100
  for (timer = 0; timer <= 100; timer++) {
    setTimeout("changeOpac(" + timer + ",'" + imageId + "')",(timer * speed))
  }

  var recur_call = "rotateImage('"+place+"')";
  setTimeout(recur_call, interval);
}
</script>


<script>
  rotateImage('rImage');
</script>

ตรงที่จะแทรกโค๊ดใช้ html เหมือนเดิม ดังนี้

<div id="divgalid" style="width: 200px; height: 230px; text-align: center; float: right; background: #eee;">
  <img name="rImage" src="http://www.palapanyo.com/gal/random/w150/chaitiyo.jpg" id="imggalid" />
</div>
