Background Menu Image Does Not Display Properly

Newbie & Debugging Questions

So I am coding a RTS game, and trying to setup its menu and such.
However, when I try to display a background image for the entire screen, it does not load properly.

This is the code:

public static Texture Btexture;
	
	public static void initBackground() {
		try 
			{
				Btexture = TextureLoader.getTexture("PNG", ResourceLoader.getResourceAsStream("Artyas_Background.png"));
			} 
		catch (IOException e)
			{
					e.printStackTrace();
			}
	}
	
	public static void Brender()
	{
		GL11.glEnable(GL11.GL_TEXTURE_2D);  
		Color.white.bind();
	
		Btexture.bind();
		
		GL11.glBegin(GL11.GL_QUADS);
		
		GL11.glTexCoord2f(0,0);
		GL11.glVertex2f(0,600);
		GL11.glTexCoord2f(1,0);
		GL11.glVertex2f(800,600);
		GL11.glTexCoord2f(1,1);
		GL11.glVertex2f(800, 0);
		GL11.glTexCoord2f(0,1);
		GL11.glVertex2f(0, 0);

		GL11.glEnd();
	}

I initialise it (Like all the other images):

public static void initStates()
	{
		MenuGUI.initBackStatic();
		MenuGUI.initStartStatic();
		MenuGUI.initExitStatic();
		MenuGUI.initStartHover();
		MenuGUI.initExitHover();
		MenuGUI.initBackground();

	}

And I render it:

case MENU:
					GL11.glColor3f(1.0f, 0.0f, 0.2f);
				//	glRectf(0, 0, 800, 600);
					MenuGUI.Brender();
					MenuGUI.BDrender();
					MenuGUI.STrender();
					MenuGUI.ETrender();
					int mousex = Mouse.getX();
					int mousey = Mouse.getY();
					//System.out.println(mousex + " - " + mousey);
					boolean leftButtonDown = Mouse.isButtonDown(0); 
					boolean rightButtonDown = Mouse.isButtonDown(1); 
					if((mousex>=50 && mousex < 200) && (mousey<500 && mousey >450))
					{
						//System.out.println(mousex + " - " + mousey);
						MenuGUI.SHrender();
						if(leftButtonDown)
						{
							state = States.GAME;
						}
					}
					if((mousex>=50 && mousex < 200) && (mousey<450 && mousey >400))
					{
						//System.out.println(mousex + " - " + mousey);
						MenuGUI.EHrender();
						if(leftButtonDown)
						{
							Display.destroy();
							System.exit(0);
						}
					}
					break;

Any help would be appreciated. I keep trying to fix this since yesterday.
