I have this program where I need to display an image on the button, but when I run the program it only shows a blue square and not the image.

To use image/icon in swing, you can setup folder structure as below :

src/
----images
----icons
----your-folder/Ventanona.java

Inside Ventanona.java can access :

new ImageIcon(getClass().getResource("/images/icono.png"))

Hope that helps you !
