Hello,

Here is the code for MediaTracker object it doesnt loads image, the image is located in package DrawImage, also what is the difference between getDocumentBase() and getCodeBase()

   package DrawImage;
     
    import java.net.*;     
    import java.awt.*;
    
    public class LoadImage extends java.applet.Applet 
    {
        Image uc  ;
        URL base;
        MediaTracker mt;       
    
    	public void init()
    	{
       		mt = new MediaTracker(this);
        	try{
            		base = getDocumentBase();
            		}catch(Exception e){}
        
        	uc = getImage(base, "src//DrawImage//java.gif");
	        mt.addImage(uc,1);
        
        	try{
	        mt.waitForAll();
        	}catch(InterruptedException e){}    
	}
    
    	public void paint(Graphics g)
	{   
        	g.drawImage(uc, 45  , 45, Color.yellow, this);
    	}        
   }
