Use dedomil.josesk.features.RLoader.loadImage(String source) method to load you Image and store it inside a javax.microedition.lcdui.Image variable

Like:

Code:

Image background = RLoader.loadImage("YourImageFile.png");

And use javax.microedition.lcdui.Graphics.drawImage(Image img, int x, int y, int anchor) method inside paint(Graphics g) method into dedomil.yourgame.Game method, before any other command, to draw your background

Like that:

Code:

g.drawImage(background, 0, 0, 0);

IMPORTANT: Load EVERY resources, including Images, before anything, i recommend using the Constructor for that, NEVER load the image just before drawing it in the same mothod

Never do that:

Code:

public void paint(Graphics g){
Image background = RLoader.loadImage("YourImageFile.png");
g.drawImage(background, 0, 0, 0);
}

That's dumb


Do that:

Code:

Image background = RLoader.loadImage("YourImageFile.png");
public void paint(Graphics g){
g.drawImage(background, 0, 0, 0);
}

Or

Code:

Image background;
public YourClass(){
background = RLoader.loadImage("YourImageFile.png");
}

public void paint(Graphics g){
g.drawImage(background, 0, 0, 0);
}
