Here is an example in jsp that insert name, city and image to database.

<%@ page import="java.sql.*"%>
<%@ page import="java.io.*"%>
<%
FileInputStream fis;
String url="jdbc:mysql://localhost:3306/test";
   try{
     Class.forName("com.mysql.jdbc.Driver").newInstance();
     Connection con=DriverManager.getConnection(url,"root","root");
     File image=new File("c:/image1.jpg");
     PreparedStatement psmt=con.prepareStatement("insert into data(name,city,image)"+"values(?,?,?)");
     psmt.setString(1,"John");
     psmt.setString(2,"Austin");
     fis=new FileInputStream(image);
     psmt.setBinaryStream(3, (InputStream)fis, (int)(image.length()));
     int s = psmt.executeUpdate();
     if(s>0) {
     %>
     <b><font color="Blue">
     <% out.println("Inserted successfully !"); %>
     </font></b>
     <% }
     else {
     out.println("Error!");
     }
     con.close();
     psmt.close();
     }
     catch(Exception ex){
     out.println("Error in connection : "+ex);
     }
%>
