Images from SQL Server in Flex DataGrid via SOAP.

I have created a Web Service in C# that delivers thumbnails from SQL Server as byte arrays.  It works.  In C# I can create a client that will display the images using the web service.  I am trying to convert the byte array to a bitmap and use that as the source to a datagrid column with an <mx:Image> in the itemRenderer.  I have tryed several different approaches.

Using the web service and displaying text is straight forward and I have no problem there.  When I try to use the byte array to create bitmap data and use it in a bitmap object as the source for the <mx:Image> the image is blank.  I wonder if this is an encoding or endean issue.  I'm not sure if there is a stream object as in C# that can be used without file I/O.  I can't see how to use the loader as it requires the result be available in a completion event and therefore limits returning it from a function.  Any direction would be appreciated.  Here is my code:
