Depends on how you want to do it. Normally best as


BufferedImage bi = javax.imageio.ImageIO.read(getClass().getResource("/MyImage.png"));

to display an image from a file see here

http://www.objects.com.au/java/qa/926375938.html

Using that method the image can be where you want it

Easit way to display an image is using a JLabel, see here for an example

http://java.sun.com/docs/books/tutorial/uiswing/components/icon.html

When loading it as a resource as in this example the image needs to be located in your classpath

My apologized. The question should be in j2me zone.

I inserted  the image file into res directory under my project.
And I still getting an exception: java.io.IOException.

Please post your code. Something like

getResource("/res/MyImage.png")

should be used

protected void paint(Graphics g){

OK, so make that
image = javax.imageio.ImageIO.read(getClass().getResource("/MyImage.png"));
 

...

public void paint(Graphics g){ // possibly paintComponent if JPanel

   g.drawImage(image, 20, 20 , 0);

}

thanks, but as I wrote before my question is about J2ME programming. javax is not included in the J2ME platform.

try putting the image file i  the root directory of your jar

and make sure you load it after the midlet has completed initialising (after init() has been called)

Its working! I changed the image and it is working.

It is important to  emphasize for others , that the code for creates an immutable image was still : image = Image.createImage ("/MyImage.png")   .  I put the images only in the "res" folder,
and in the "Properties for res => Native Library => Location path" , I inserted  the "res" location path, that is "MyProject/res".

thanks a lot objects.
