got "Failed to load resource: cancelled" Error when using Jquerymobile in difference browsers

Here is my code
<html>
<head>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0a3/jquery.mobile-1.0a3.min.css" />
<script src="http://code.jquery.com/jquery-1.5.min.js"></script>
<script src="http://code.jquery.com/mobile/1.0a3/jquery.mobile-1.0a3.min.js"></script>
</head><body>
<div>
<img src="avatar2.jpg" width="80" height="80" >
</div>
</body>
</html>

The image did not show in any browsers (firefox, safari, chrome). If I commented out the jquerymobile library, the image showed up.

here are the error msg in browsers
firefox: no error msg showed
safari: Failed to load resource: cancelled
chrome: XMLHttpRequest cannot load file:///pathtomyhtml/my.html Origin null is not allowed by Access-Control-Allow-Origin.
