A program can't solve

java.io.IOException

- com.siemens.mp.ui.Image.<init>(), bci=109

- javax.microedition.lcdui.Image.createImage(), bci=10

- com.linuks.demo.PasswordManagerMidlet.<init>(), bci=48

- java.lang.Class.newInstance(), bci=0

- javax.microedition.midlet.Main.main(), bci=83

This is a exception of the project "PasswordManager" software on the mobile.It's a finished project already.But i want to improve it in my way.There has no images in the software.I want to add some pics to improve the software's interface.
The centense like this:
try {
addImage=Image.createImage("/add.png");
} catch (IOException e) {
e.printStackTrace();
}
lstMain.append("Add", addImage);
But it will appear the exception above.Be busy doing it the whole day,has no result.
Get the inclusion,maybe the pics path was error.
