Though the documentation says Image is Serializable, it is in fact not so
because it contains objects  which are not serializable.

Here is a small test case which shows the bug (modify the test to supply
a .gif file).  This bug critically impacts
core functionality of Java Studio.

abhilasha{pjajoo}256: cat ImageBug.java
import java.awt.*;
import java.io.*;

public class ImageBug {
    public static void main(String[] args) {
	
	Image img = Toolkit.getDefaultToolkit().getImage("Button.gif");
	System.out.println("Img = " + img);

	try {
	    ObjectOutputStream os = new ObjectOutputStream(
					new ByteArrayOutputStream());
	    os.writeObject(img);
	    os.close();
	} catch (Exception e) {
	    e.printStackTrace(System.out);
	}
    }
}
