And we will need more details..... how do you display your image ? By hand, in a JLabel ?
If it is in a JLabel it might be done automatically.

hi..I have taken a JLayeredPane in that iam adding JLabel.On to this JLabel iam able to retrieve the image from database but the thing is if the size of the image is so large thn i need to set the size of the image of same size of my JLayeredPane (250x250)[widthxheight]
In Mysql i hve created database name---skybirds,tablename--photo,column names---image1 LONGBLOB,image2 LONGBLOB,image3 LONGBLOB.so in short my requirement is any size of the image should be set manually while retrieving from database.
in my code i am retreiving image from database on to a label which is placed in JLayeredPane.so the image should be set in to that JLayeredPane if that image size is very large also.
I am sending my code also.jst look at the JLayeredPane(lp2).for remaining part i didnt write code.jst for retrieving image only i hve written code.if u want to run this code jst create database name---skybirds,tablename--photo,column names---image1 LONGBLOB,image2 LONGBLOB,image3 LONGBLOB.
i hope u hve understood my requirement and iam eagerly waiting for solution from you.thank u for responding quickly.

Build a class that extends JLabel
a constructor that receives the file to display or an Icon
add a setIcon() method that overload setIcon() of JLabel
overload the paint() method of that class
and redraw yourself the image

class ImageLabel extends JLabel {
   Image image;
   ImageObserver imageObserver; 

   // constructor with filename		
   ImageLabel(String filename) {
	  ImageIcon icon = new ImageIcon(filename);
	  image = icon.getImage();
	  imageObserver = icon.getImageObserver();
   }

   // constructor with icon
   ImageLabel(ImageIcon icon) {
	  image = icon.getImage();
	  imageObserver = icon.getImageObserver();
   }

   // overload setIcon method
   void setIcon(ImageIcon icon) {
	  image = icon.getImage();
	  imageObserver = icon.getImageObserver();
   }

   // overload paint()
   public void paint( Graphics g ) {
	   super.paint( g );
	   g.drawImage(image,  0 , 0 , getWidth() , getHeight() , imageObserver);
   }
}

You don't have to resize the image, the code does it for you.
I have tested it .. it works

For the Labels that display image replace "new JLabel()" by "new ImageLabel()"

Try this if it helps...

<code>
ImageIcon tinyPicture= new ImageIcon(filename);
Image image= tinyPicture.getImage();
image = image.getScaledInstance(200, -1, image.SCALE_SMOOTH);
tinyPicture.setImage(image);
imageLabel1.setIcon(tinyPicture);
</code>

Thanks,

Rupali

			imageLabel1 = new ImageLabel(filename);

Nothing more complicated
