    Default [SOLVED] .gif image becomes black and white

    My program is put together from a few online tutorials because I'm new to working with images. It displays the image I expected it to, but it's black and white (took me a while to recognize it!)

    Since the code is big, I'm only posting what I think is relevant.

    public class Board extends JPanel implements ActionListener {
     
    	public MovableObject[] movables; 
     
    	public Board(){
    		movables = new MovableObject[MAX_MOVABLE_OBJECTS];
    		movables[0] = new MovableObject(0);  // (0) - player character;
    	}
     
    public void paint(Graphics g) {
    		super.paint(g);
    		Graphics2D g2d = (Graphics2D) g;
     
    		g2d.drawImage(movables[0].getImage(), movables[0].getX(), movables[0].getY(), null);  
    	}
     
     
    public class MovableObject {
     
    	BufferedImage still;
    	AnimatedSprite sprite;
     
    	public MovableObject(int spriteRefNum) {
     
    		sprite = sprites[spriteRefNum];
    		still = sprite.getCurrentImage();
    	}
     
    	public Image getImage() {
    		return still;
    	 }
    }
     
     
    static public AnimatedSprite[] sprites = new AnimatedSprite[MAX_SPRITES_GLOBAL]; 
     
     
    public class AnimatedSprite {
     
    	private double x; // upper left coordinates of the sprite
    	private double y;
    	private double lastX; // the coordinates the sprite was at the previous frame
    	private double lastY;
     
     
    	private HashMap<String, int[]> frames;
     
    	private BufferedImage[] images; // all the images of this AnimatedSprite
     
    	private String currentAnim;  // the current 'state' or animation that the sprite is in
     
    	private int currentFrame;
     
    	private int[] currentFrameSet;  // current set of frames being used
     
    	public AnimatedSprite(BufferedImage[] images) {  // class constructor
    		this.images = images;
    		frames = new HashMap<String, int[]>();
    	}
     
    	public void addNewAnimation(String name, int[] set) {
    		frames.put(name, set);
    		setAnimation(name);
    	}
     
    	public void setAnimation(String name) {  // Sets the current animation of the Sprite
    		if(frames.containsKey(name)) {
    		currentAnim = name;
    		currentFrameSet = frames.get(currentAnim);
    		currentFrame = 0;
    		}
    	}
     
    	public void setLocation(double x, double y) {  // upper left corner
    		this.x = x;
    		this.y = y;
    	}
     
    	// added ************************
    	public BufferedImage getCurrentImage() {
    		return images[0];
    	}
    	// *****************************
     
    	public int getWidth() {  // Gets the width of one frame
    		return images[0].getWidth();
    	}
     
    	public int getHeight() {  // Gets the height of one frame
    		return images[0].getHeight();
    	}
    }
     
     
    public class ImageUtil {
     
    	public static BufferedImage loadImage(String ref) {
    		BufferedImage bimg = null;
    		try {
     
    			bimg = ImageIO.read(new File(ref));
    		} catch (Exception e) {
    			e.printStackTrace();
    		}
    		return bimg;
    	}
     
    	 public static BufferedImage[] splitImage(BufferedImage img, int cols, int rows) {
    			int w = img.getWidth()/cols;
    			int h = img.getHeight()/rows;
    			int num = 0;
    			BufferedImage imgs[] = new BufferedImage[w*h];
    			for(int y = 0; y < rows; y++) {
    				for(int x = 0; x < cols; x++) {
    					imgs[num] = new BufferedImage(w, h, img.getType());
    					// Tell the graphics to draw only one block of the image
    					Graphics2D g = imgs[num].createGraphics();
    					g.drawImage(img, 0, 0, w, h, w*x, h*y, w*x+w, h*y+h, null);
    					g.dispose();
    					num++;
    				}
    			}
    			return imgs;
    		}
    }

    Default Re: .gif image becomes black and white (against my wishes)

    It seems that the code works with some pictures, although I can't figure out the rule (which format or color depth), but it's kind of solved.
