Anyone know how to prevent thsi from hapening, ie so it doesn't stop the JS refresh?

instead of refreshing the page, only refresh the image element. Here's how:

Code:

<html>
<head>
    <title>Untitled Page</title>
    <script type="text/javascript">
        function grabImage() {
            var imgFrm = document.getElementById('imageframe');
            var img = document.createElement("img");
            img.setAttribute('src', 'http://77.46.140.219/axis-cgi/mjpg/video.cgi?resolution=CIF&dummy=1234987014475');
            imgFrm.removeChild(imgFrm.firstChild);
            imgFrm.appendChild(img);
            setTimeout(grabImage, 10000);
        }
    </script>
</head>
<body onload="grabImage();">

<div id="imageframe"><img /></div>

</body>
</html>

NOTE: if you have to refresh the image, it's not really a mjpeg stream. It's just an image that get's updated at an interval. an mjpg stream should update itself without any JS in firefox on the Desktop or on the NIT's browser.
