I have the following HTML web page:
<html>
<body>
<IMG SRC='http://85.46.64.155/axis-cgi/mjpg/video.cgi'>
</body>
</html>
This web page displays the feed of an IP camera streaming MJPEG data. You can try the above code here: http://jsfiddle.net/jU4aq/ (it doesn't work from IE)
My question is how I can make a snapshot of that feed. Basically I want to add a button that when the user clicks on it, a dialog will pop up and will give you the option to save the image.

Your stream doesn't seem to be working right now but try a bit of canvas javascript, like:
<html>
<body>
<IMG id="myImage" SRC='http://85.46.64.155/axis-cgi/mjpg/video.cgi'>
<input type="button" id="save" value="Save to PNG">
<script type="text/javascript">
document.getElementById('save').onclick = function () {
var c = document.createElement('canvas');
var img = document.getElementById('myImage');
c.width = img.width;
c.height = img.height;
var ctx = c.getContext('2d');
ctx.drawImage(img, 0, 0);
//window.location = c.toDataURL('image/png');
window.open(c.toDataURL('image/png'))
};
</script>
</body>
</html>
Use AXIS api to get snapshot, you can get it here: http://www.axis.com/techsup/cam_servers/dev/cam_http_api_index.php
In you case URL is "http://your.server/axis-cgi/jpg/image.cgi"
Also you can use additional parameters, such as resolution and compression
