How about bulding a 3rd party image viewer ( http://www.yiigo.com/guides/csharp/how-to-create-web-viewer.shtml
) to help display images with the help of some professional manual imaging toolkits( http://www.yiigo.com/guides/vbnet/
)? I am not very sure about that whether it is the best solution to this problem. But you can google it and have a try. I hope you success. Good luck.
