My code given below works fine. U can try if u want

public void sendImageFile(HttpServletResponse response)
{
        FileInputStream in=null;
        File f = null;
        try
        {
                f = new File("webapps/Plasma/graphs", "image.gif");
                in = new FileInputStream(f);
                                
                response.setContentType("image/gif");
                int size = (int)f.length();
                response.setContentLength(size);
                byte buffer[] = new byte[size];
                in.read(buffer);
                response.getOutputStream().write(buffer);
        }
        catch(NullPointerException e)
        {
        System.out.println(" NP xpn in sendImageFile "+ e.getMessage());
        }
        catch(FileNotFoundException e)
        {
        System.out.println(" FNF Xpn in SendImageFile "+ e.getMessage());
        }
        catch(IOException ee2){ log("Trouble: " +ee2);}
        finally
        {
        try
                {
                        response.getOutputStream().close();
                }
        catch(IOException ee2){ log("Trouble: " +ee2);}
}
}
