JCo - retrieving images (Urgent)

Hi,

I have to retrieve an image from SAP and render it in the portal. I get the data via Jco as a table and from the table I retrieve a binary stream. When I write the stream to a file the image doesn't display. Funny thing is, if I take the same image that is in SAP and read it from a file, the input stream data seems completely different from the data I get from SAP. Is something happening in the background that I am not aware of? Any help or ideas would be greatly appreciated
