Well, I don't want to be dependent upon an internet connection, so I did manage to figure out how to reference a local file on my computer instead.  However, I can't figure out how to make it relative to the current directory, so it doesn't survive being network loaded form another computer, or being sent via e-mail.

This URL right here makes it offtopic for a linux users list, but ...

The right way to do this is to include candle.gif in the jar file that
contains your app.  If it's at the root, you can basically do:

import javax.imageio.ImageIO;
import java.awt.Image;

Class Foo
{
    Image image = ImageIO.read(Foo.class.getResourceAsStream('/candle.gif'));
}

if Foo is in package com.foo.bar, you can also put candle.gif in
/com/foo/bar/images/candle.gif in the jar file, and call
getResourceAsStream('images/candle.gif') ... relative pathnames are
expanded relative to the base of the package path.  Check out the 
javax.imageio package and Class.getResourceAsStream javadoc entry
for more background.
