How do you rotate an image using jQuery-rotate plugin?
I have tried the following and it doesn't seem to work:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>View Photo</title>
<script type="text/javascript" src="scripts/jquery.js"></script>
<script type="text/javascript" src="scripts/jquery.rotate.1-1.js"></script>
<script type="text/javascript">
var angle = 0;
setInterval ( function (e) {
rotate();
}, 100 );
function rotate() {
angle = angle + 1;
$('#pic').rotate(angle);
}
</script>
</head>
<body>
<img border="0" src="player.gif" name="pic" id="pic">
</body>
</html>
Other methods that are supported by most browsers are wanted too, thanks!

You've got a 404 on jQuery and the jQuery plugin. Because of that, your page is throwing a JavaScript error, that $ is not defined.
You need to learn basic JavaScript debugging techniques. A quick search found this article that looks like a good place for you to start:
Your logic for rotating the image is right. It will work if executed when the document is ready.
<script type="text/javascript">
//<![CDATA[
var angle = 1;
$(document).ready(function() {
setInterval(function() {
$("#pic").rotate(angle);
/* angle += 1; Increases the rotating speed */
}, 100);
});
//]]>
</script>

Once you fix your jquery include issues, you can fix your script. Your syntax is wrong: Here is the fix:
<script type="text/javascript">
//<![CDATA[
var angle = 1;
$(document).ready(function(angle) {
setInterval(function(angle) {
$("#pic").rotate(angle);
/* angle += 1; Increases the rotating speed */
}, 100);
});
//]]>
</script>
