Loading ImageIcon from JAR or file system

I have a simple program that needs to display images. I know how to do this running the code from Eclipse and I know how to do it running from a JAR file, but I'd like a solution that works in both cases.

Eclipse project is as such:

- Project (java)
  - src
    - controller
      - Main.java
    - ui
      - Display.java
  - images
    - image.jpg

The code snippet that works from within Eclipse:

ImageIcon image = new ImageIcon("images/image.jpg);

The one that works for a JAR (all in a single JAR file):

java.net.URL imgURL = getClass().getResource("/images/image.jpg");
ImageIcon image = new ImageIcon(imgURL);

What would I need to change in order to get a single piece of code that works in both situations?
