First off, the 'getImage' and 'setImage' methods are in the Actor class -- not the World class. So, you cannot use them here. The getter/setter methods for the world background image are 'getBackground' and 'setBackground'. If you were to use 'getBackground' on your world that has a default image set to the class, it will not be the same exact image if the source was not the same size as that of the world -- it will either be tiled or cropped. You will need to get the image from the file and scale it to the world; then set it as the new background image of the world. For example:

GreenfootImage bg = new GreenfootImage("filename.jpg"); // adjust filename as needed
bg.scale(getWidth(), getHeight());
setBackground(bg);

Also, and I do not know if you copy/pasted funny or not--but, it appears you have two constructors in the same class with different class names -- namely 'LevelScreen' and 'LevelOne'. The compiler will have a fit over that. Insert my three lines after line 15 and remove lines 5 through 10.
