is it correct? Code Amazon s3

<script type="text/javascript" src="iuembed.AmazonS3.js"> </script>

<script language="javascript">

var iu = new ImageUploaderWriter("ImageUploader", 650, 450);

// If you do not want to use ActiveX or Java version, set the appropriate

// property to false.

iu.activeXControlEnabled = true;

iu.javaAppletEnabled = true;

iu.activeXControlCodeBase = "ImageUploader6.cab";

iu.javaAppletCodeBase="./";

iu.addParam("LicenseKey", "xxxxx-xxxxx-xxxxx-xxxxx-xxxxx;xxxxx-xxxxx-xxxxx-xxxxx-xxxxx");

var as3 = new AmazonS3Extender(iu);

as3.setAWSAccessKeyId("AccessKey");

as3.setBucket("Bucket");

as3.setBucketHostName("https://s3.amazonaws.com/");

// ... initialize params as described in the next topic ...

as3.gestSourceFile().SetPolicy(???);

as3.gestSourceFile().SetKey("folder/");

as3.gestSourceFile().SetAcl("public-read-write");

as3.gestSourceFile().SetSignature("Secretkey");

// As soon as you call this method, all necessary HTML code is inserted

// into the page on the current position. Alternatively, you can

// get the string with appropriate HTML code using the getHtml method,

// and write it to the necessary position manually (maybe with some modifications).

iu.writeHtml();

</script>

Is it correct this code?

Post the correct code please.

Thanks
