This script works in Netscape 3.0 and IE 4.0 but errors in IE 3.0
It claims an undefined variable with the load image () statment.

<SCRIPT LANGUAGE="JavaScript1.1">
<!-- Hide script
var Inc=0;
var Max=4;



var ImageArray = new Array();
ImageArray[1] = new Image();
ImageArray[1].src = "Image1.gif";
ImageArray[2] = new Image();
ImageArray[2].src = "Image2.gif";
ImageArray[3] = new Image();
ImageArray[3].src = "Image3.gif";
ImageArray[4] = new Image();
ImageArray[4].src = "Image4.gif";


function LoadImage()
{
    Inc++;
    if (Inc > Max) {
      Inc=1;
    }
    document.STUFF.src=ImageArray[Inc].src;
    setTimeout("LoadImage()",8000);            


}
// -->
</SCRIPT>
</HEAD><BODY onload="LoadImage();">

<img src="Image2.gif" width="468" height="60" name="STUFF">


</BODY></HTML>

Internet Explorer 3.0 is NOT compatible with Netscape Navigator 3.0, it is compatible with Netscape 2.0!!! (it even admits that in the navigator.appVersion)
userAgent=Mozilla/2.0 (compatible; MSIE 3.02; Update a; Windows NT)
appVersion=2.0 (compatible; MSIE 3.02; Update a; Windows NT)

Therefore, it does not implement "JavaScript1.1" and completely ignores your code. When onload tries to call LoadImage(), the function is not defined.

There is really nothing you can do to make your code work in IE3, because the Image-object is not implemented. By adding:
<script language="JavaScript">
  function LoadImage() {}
</script>
IN FRONT of your other code, the page will load without errors, but of course, it won't do what you want it to do!

sorry for the bad news, but of all the people trying to replace images in IE3, I don't know anybody who has done it (well, there are workarounds that involve frames, reloading the page or the <iframe> tag if it is absolutely necessary, but they tend to be rather ugly!)

I do Not wish to use a frames page hack. However what about the possibility of loading a diferant image if the user hits a back button from a link? (Of corse this should be tied to a browser detect script and only execute for IE3.)
