I want to change image src after some time to another (after 3 secs in example) and if there arent more images then turn into the first one again. In example I have 3 different image sources (gfx/img1.jpg, gfx/img2.jpg, gfx/img3.jpg).

 

This is part of my code but something is wrong there. Can someone help?

 

   <script type="text/javascript">
      var i = 0;
      var image = document.getElementById('changeimage');
      function changeImage() {
         if (i == 0) {
            image.src = 'gfx/img1.jpg';
            i = 1;
         } else if (i == 1) {
            image.src = 'gfx/img2.jpg';
            i = 2;
         } else {
            image.src = 'gfx/img3.jpg';
            i = 0;
         }
         setTimeout('changeImage()', 3000);
      }

   </script>

</head>

<body onload="changeImage();">
   <img id="changeimage" src="gfx/img1.jpg" />
