Hi,

I was trying to integrate a scanner with my application. After a long  
struggle i succeeded in integrating, Now i could see the captured image  
in my browser, But now i need to upload that image in buffer to the file  
system(Server Side) or to data base.

How to carry out this any suggestions?

Thanks,  
Ratnavel.
