<script>
function createUploader(){
var uploader = new qq.FileUploader({
element: document.getElementById('file-uploader'),
action: 'php.php',
});
}
// in your app create uploader as soon as the DOM is ready
// don't wait for the window to load
window.onload = createUploader;
</script>
</head>
<body>
<div id="file-uploader">
<noscript>
<p>Please enable JavaScript to use file uploader.</p>
<!-- or put a simple form for upload here -->
</noscript>

ALSO-as you can see i'm passing data through session is this correct or should it be done another way also sorry i know its long now is there a way to add a <input type="text" name="description">
to the html and have the file upload script put it in the mysql as it does the file name, time and album
thanks for your time
