I can't figure out exactly how to make this work. I am new to PHP by the way.
Here is what I current have (zerkms's solution), and it still isn't working for some strange reason:
here is a link to the page on the server:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Demo</title>
<?php
$srcmsg = 'http://www.newyorker.com/online/blogs/photobooth/NASAEarth-01.jpg';
?>
<script type="text/javascript">
//<![CDATA[
//
var msr = "<?php echo $srcmsg; ?>";
window.onload = document.getElementsByTagName('img').src= msr;
//]]>
</script>
</head>
<body>
<img src="#" alt="Picture of the world" height="42" width="42" />
</body>
</html>
