Yes, that page probably does answer your question. Basically, you want this javascript:
```
<script type="text/javascript">
document.getElementById('image').src = "yourpicture.png";
</script>
```
Except you want to replace the "yourpicture.png" with the function you wrote to generate the correct path to the image on disk, so...
```
<script type="text/javascript">
document.getElementById('image').src = displaydate();
</script>
```
Of course, you might need to modify this a bit for your own uses, the getElementById will take as an argument whatever the id attribute of your < img > tag is. You probably want to execute the above javascript after your page has loaded, i.e.:
```
<html>
<head>
<script type="text/javascript">
function load()
{
document.getElementById('image').src = displaydate();
}

function displaydate()
{
//your displaydate() function here
}
</script>
</head>

<body onload="load()">

<img src="nothing.jpg" id="image" name="image"/>
</body>
</html> 
```

You should just need to change this line

document.write("http://host1/Shared/" + year + "/" + month + "/" + day + "/cpu_abs.gif");

to

return "http://host1/Shared/" + year + "/" + month + "/" + day + "/cpu_abs.gif";
