And here are the two functions
public static Image getTexture(String filename){
Image img = null;
img = Toolkit.getDefaultToolkit().createImage(filename);
System.out.println("Image!");
return img;
}

public static Image getTexture(String filename, int indexX, int indexY){
BufferedImage tempImg = null;
Image img = null;

if(filename == null)
return null;
try{
tempImg = ImageIO.read(Art.class.getResource(filename));
img = tempImg.getSubimage((indexX * TEX_WIDTH), (indexY * TEX_HEIGHT), TEX_WIDTH, TEX_HEIGHT);

}catch(Exception e){
e.printStackTrace();
}
return img;
}


and the paint method:
public void paint(Graphics g){
super.paint(g);
if(gamestate == Gamestate.MainMenu){
g.drawImage(MainMenu.background, 0, 0, this);
g.drawImage((Art.getTexture("GUI/tile.png", 1, 1)), 0, 20, this);

MainMenu.play.setVisible(true);
MainMenu.options.setVisible(true);
MainMenu.load.setVisible(true);
}
else if(gamestate == Gamestate.Credits){
g.setColor(Color.BLACK);
g.fillRect(0, 0, WIDTH, HEIGHT);
}
else if(gamestate == Gamestate.Settings){
g.drawImage(SettingsMenu.background, 0, 20, this);
}

if(OverlayMenu){
g.setColor(new Color(0, 0, 0, 126));
g.fillRect(0, 0, WIDTH, HEIGHT);
}
}

Can someone please help me!

Where do you use the first function? Unless I'm missing something, it's never called in any of the code you posted. Or were you swapping them out in the paint() method, for testing?[/quote]
Im just swapping them out to test.

Are you sure you're actually getting a valid image back? Looking at the error messages makes it seem like you're not..[/quote]
Im not sure I am, can you tell me a way to check please

[color="#1C2837"]Just out of curiosity, why are you using two different methods to get the image? In your first getTexture() method,[color="#1c2837"][/quote]

[color="#1c2837"]That was some old code, I was testing to see if different ways of obtaining the resource would fix it. Here are my new, much cleaner methods (that still dont work):

[color="#1c2837"]

package me.spacekid434.Exordium;

import java.awt.image.BufferedImage;
import javax.imageio.ImageIO;

public class Art {

public static final int TEX_WIDTH = 16, TEX_HEIGHT = 16;

public Art(){

}

public static BufferedImage getTexture(String filename){
try {
BufferedImage img = ImageIO.read(Art.class.getResource(filename));
return img;
}catch (Exception e){
e.printStackTrace();
}
return null;
}

public static BufferedImage getTexture(String filename, int indexX, int indexY){
try{
BufferedImage tempImg;
BufferedImage img;

tempImg = ImageIO.read(Art.class.getResource(filename));
img = tempImg.getSubimage((indexX * TEX_WIDTH), (indexY * TEX_HEIGHT), TEX_WIDTH, TEX_HEIGHT);

return img;
}catch(Exception e){
e.printStackTrace();
}
return null;
}
}

Can't you just do the standard...
if (img == null)
{
//do something to inform you that the image wasn't loaded
}

Also...
g.drawImage((Art.getTexture("GUI/tile.png", 1, 1)), 0, 20, this);
I believe, when you're trying to get things from subfolders, there should be a leading slash. Example: "/GUI/tile.png". Maybe try placing the image in the main folder and try to access it with just the file name.
