Rendering an image from Amazon S3 on VF page

Iam using Amazon toolkit to integrate SF with Amazon S3.

I want to render the content(image) of files in a bucket when bucket is selected from a selectlist. Like ListBucket, I am calling a method 'getObject' which in turn calls the webservice operation 'GetObject' from S3 class. I can see the request and response(200) in my developer console but there is an exception

ERROR: Web service callout failed: Unable to parse callout response. Apex type not found for element Status.User-added image

Came across the following thread where the mismatch in the return element was giving this error.
Pls check the Apex class you have created using the WSDL and confirm if the return element is Status.

I have to Change GetObjectResult orginal code to also get status and  field_order

public class GetObjectResult { 
public S3.MetadataEntry[] Metadata; 
public String Data;
public DateTime LastModified; 
public String ETag; 
public Status Status; 
private String[] Status_type_info = new String[]{'Status','http://s3.amazonaws.com/doc/2006-03-01/','Status','1','1','false'}; 
private String[] Metadata_type_info = new String[]{'Metadata','http://s3.amazonaws.com/doc/2006-03-01/','MetadataEntry','0','-1','false'}; 
private String[] Data_type_info = new String[]{'Data','http://www.w3.org/2001/XMLSchema','base64Binary','1','1','true'}; 
private String[] LastModified_type_info = new String[]{'LastModified','http://www.w3.org/2001/XMLSchema','dateTime','1','1','false'}; 
private String[] ETag_type_info = new String[]{'ETag','http://www.w3.org/2001/XMLSchema','string','1','1','false'}; 
private String[] apex_schema_type_info = new String[]{'http://s3.amazonaws.com/doc/2006-03-01/','true'}; 
private String[] field_order_type_info = new String[]{'Status','Metadata','Data','LastModified','ETag'};

}


Now the above error is Gone.

I need to parse the xml response and render the image on VF page. Can you suggest me any way?
