my problem..how to show the resulted images when the search button is click

You need a couple of things added to your code.
Definition for the yeahFrame class.
Code to create the image.
Code to show the image.

here is my yeahFrame class

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.sql.*;
import java.io.*;
import java.awt.image.*;


public class yeahFrame extends JFrame
{
    JLabel m1,m2,m3,m4;
    BufferedImage bimg;
    JPanel jp;
    JLayeredPane p1,p2;
    InputStream is;
    
    public yeahFrame()
    {
        JFrame frame = new JFrame("Search Photos");
        frame.setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE);
   
        frame.setSize(1024,750);
        frame.setLocation(20,20);
        frame.setVisible(true);
        
        m1 = new JLabel();
        m2 = new JLabel();
        m3 = new JLabel();
        m4 = new JLabel();
        
        p1 = new JLayeredPane();
        p2 = new JLayeredPane();

    }
    public static void main(String args[])
    {
        new yeahFrame();
    }
}

ok here is the problem..i dont know what to use in order to retrive the images search by the user..what method should i use?

i dont know what is the code to create and show the image..

try
        {
            Class.forName("com.mysql.jdbc.Driver");
            Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","nbuser");
            
            
            Statement st1=conn.createStatement();
            ResultSet rs = st1.executeQuery("select img from pic where caption LIKE 'h%'");
    
                
            while(rs.next())
            {
                Blob blob = rs.getBlob(1);
                in = blob.getBinaryStream();
            }
            rs.close();
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }

i used this one to retrieve images from database but how to display all the resulted images in a jlabel? help please

ok all i have to do is when i click the "search button", it will performed the query statement..and all the resulted images will be displayed in the yeahFrame() class or the second class..how do i do that??

Several steps involved:
Get the bytes for the image
Convert the bytes to an image icon object
Create a label with that icon or set an existing label's icon

Well, I can see you know how to add components to a Gui, as you've done that. And, I can see that you know how to read a Blob from the DB, since you do that. So, I assumed, that all you needed was help on how to go from the images binary contents to an Image. Well, as I said see the API docs for ImageIO.

..how do i do that??

Not by waiting on us to do it for you which is what this comment makes it look like you're doing.
