    Sometimes, we need to rotate images on ours web pages, it may be ads or some simple images.Below you'll find the code for implementing the same.
    You can create as many image rotations you want, you just need to specify the urls of the images in an Array, and the object where the image will be shown. The function RotateImages is called with the Array/Img Object number, and at what index of the array the rotation should start.

    HTML:
    <html>
      <head>
      <title>Image Rotate
      </head>
      
      <body>
      <img src="" name="Rotating" id="Rotating1" width=100 height=100>
      <img src="" name="Rotating" id="Rotating2" width=100 height=100>
      
      
      <script language="JavaScript">
      var ImageArr1 = new Array("Picture(3).jpg","Picture(1).jpg","Picture(2).jpg");
      var ImageHolder1 = document.getElementById('Rotating1');
      
      var ImageArr2 = new Array("Picture(5).jpg","Picture(6).jpg","Picture(7).jpg");
      var ImageHolder2 = document.getElementById('Rotating2');
      
      function RotateImages(whichHolder,Start)
      {
      	var a = eval("ImageArr"+whichHolder);
      	var b = eval("ImageHolder"+whichHolder);
      	if(Start>=a.length)
      		Start=0;
      	b.src = a[Start];
      	window.setTimeout("RotateImages("+whichHolder+","+(Start+1)+")",1500);
      }
      
      RotateImages(1,0);
      RotateImages(2,0);
      
      </script>
      
      </body>
      </html>

    Well, this script rotates the image at a preset timed interval, but for sliding the image, u'll need to change the position of the image using a javascript timer.
    u can gradually increase the left css value, then it'll slide from left to right!

    You'll need to create a two-dimensional array in this case! Try it out and keep us posted with code snippets.

    I like simplicity, especially with code. After wasting hours trying to tweak a flashy image rotation Javascript, complete with .js files to include, I gave up, called up the Google, and found this wonderfully simple code from a throwaway response on an online forum:

    Here’s how it works. See the div labelled “home-photo”? That wraps around the image that is to be replaced with other images. The img tag within the home-photo div has its own id=”photo” element which, no surprise, is called in the var ImageHolder1 = document.getElementById(’photo’). If you want to change the id=photo element to, say, id=xyz then you just change ‘photo’ to ‘xyz’ in the var ImageHolder1 = document.getElementById(’xyz’) line. (By the way, ‘var’ is shorthand for variable. You’re just setting a variable that grabs the element tagged id=”xyz”.)

    To specify the images to rotate, just add file path and image names to the var ImageArr1 = new Array(”", “”, “”) line. Be careful to wrap each file path and image name with double quotes with a comma between each and you’ll be fine.

    The last element to set is the ‘3500′ at the end of the window.setTimeout(..) line. That’s the number of milliseconds between the display of each image.

    This code does not have fancy wipes, dissolves, or other whizzy features. But it doesn’t require include references to javascript files and other complexity that can go horribly wrong horribly fast. Just tweak this code and drop the Javascript part at the bottom of your web pages or templates (so it doesn’t get in the way of search bots). The image, the “home-photo” div in this example, goes where it goes in your design.

    Hello friends,

    I was quite interesting to view those expert sharing their expertise over here.
    Please help me to solve my conflict over "rotating image" issue.

    I have a webpage and the header image was set in my CSS as 'header-bg.jpg'. I would like to add more than 1 image in my header, meaning that the header image will rotate one to another after few seconds.

    Please help me to work on the right coding.

    This is my CSS:

    Code:
    /* CSS Document */
    
    * {    margin:0; padding:0; font-size:100%;}

    A simplified version with just one set of images...with some URLs attached to the images...The timeout is in miliseconds...3000 = 3 seconds...

    Hope this helps...

    Code:
    <body>
    <a id="imageurl" ><img id="Rotating1" border="0"></img></a>
    <script language="JavaScript">
      
       function RotateImages(Start)
      {
          var a = new Array("image1.jpg","image2.jpg","image3.jpg", "image4.jpg");
          var c = new Array("url1", "url2", "url3", "url4");
          var b = document.getElementById('Rotating1');
          var d = document.getElementById('imageurl');
          if(Start>=a.length)
              Start=0;
          b.src = a[Start];
          d.href = c[Start];
          window.setTimeout("RotateImages(" + (Start+1) + ")",3000);
      }
      
      RotateImages(0);
      
      </script>
    
    </body>

    This code is great! I have a quick question - well two questions.

    1) Is there anyway to have my three images rotate once and then stop?

    2) Can I use some Javascript so the rotation only occurs on the home page of my site and not on any subsequent pages?

    Thank you!
    Rachel

    Hi experts,

    I saw enough codes on the internet telling me how to Swap Image between images. But I want someone to tell me how to swap between images and Flash .swf files. My design was after a user clicks on a thumbnail on the top of a web page, the bigger picture below that will swap accordingly. Those bigger pictures include be both .jpg images or .swf files. Thanks a lot!!!!!

    I just wanted to thank you for this code snippet, I have been scouring for a small fast loading script that worked in all browsers (at least ie6 and above) and had the exact features of rotation and url's assigned to each one. I was looking at jquery scripts, which are awesome, but it's just too much overhead for my project. I am hand coding a site and I want: 1) no external libraries 2) small as possible overhead 3) xhtml 1.0 transitional certified

    You helped me accomplish 1 and 2, here is 3:

    Code:
    <a id="imageurl" name="imageurl"><img src="Rotating1" id="Rotating1" border="0" alt="Rotating1" name="Rotating1" /></a>
    <script language="javascript" type="text/javascript">
      
       function RotateImages(Start)
      {
          var a = new Array("1.jpg","2.jpg","3.jpg", "4.jpg");
          var c = new Array("url1", "url2", "url3", "url4");
          var b = document.getElementById('Rotating1');
          var d = document.getElementById('imageurl');
          if(Start>=a.length)
              Start=0;
          b.src = a[Start];
          d.href = c[Start];
          window.setTimeout("RotateImages(" + (Start+1) + ")",3000);
      }
      
      RotateImages(0);
      
      </script>
    
    Minor changes, I know, but if someone wants/needs xhtml 1.0 transitional there it is. I started out going for xhtml 1.0 strict, but it become to restraining (see: bitchy)
    Thank you so much, I hope someone finds this useful!

    Anyone have an idea as to how to make the rotation pause on mouseover? If I find it first, I will post back..

    Code:
    <a id="imageurl" name="imageurl"><img src="Rotating1" id="Rotating1" border="0" alt="Rotating1" name="Rotating1" onmouseover="StopRotation();" onmouseout="RotateImages();"/></a>
    <script language="javascript" type="text/javascript">
    
      var currentImage = 0;
      function RotateImages()
      {
        var a = new Array("1.jpg","2.jpg","3.jpg", "4.jpg");
        var c = new Array("url1", "url2", "url3", "url4");
        var b = document.getElementById('Rotating1');
        var d = document.getElementById('imageurl');
    
        currentImage++;
    
        if(currentImage>= a.length)
          currentImage=0;
    
        b.src = a[currentImage];
        d.href = c[currentImage];
    
        rotator = window.setTimeout("RotateImages(" + (currentImage+1) + ")",3000);
      }
    
      function StopRotation()
      {
        window.clearTimeout(rotator);
      }
    
      RotateImages();
    
    </script>
    
    There we go, pauses on mouseover, and then continues to next image on mouseout. Still xhtml 1.0 trasitional certified.

    Change:

    Code:
     var currentImage = 0;
    
    to

    Code:
     var currentImage = -1;
    
    so it starts on the first image in the array.

    jQuery supports all sorts of transitions. Try using it.
