Answer 1

Assuming your project is Maven-based, I would place the images in the src/main/resources folder. Maven will automatically include the files in that folder into your JAR-file.

Otherwise, this blogpost will help you out.

First Create a package(Say images) under Source Packages

copy all of your images to this package(when you create a package,a folder in the name of your package will be created inside your project src folder, so copy images to it)

You can access your Images from your program as

        URL imageurl = getClass().getResource("/images/imagename");//assuming your package name is images 
        Image myPicture = Toolkit.getDefaultToolkit().getImage(imageurl);
        JLabel piclabel = new JLabel(new ImageIcon( myPicture ));
        piclabel.setBounds(0,0,myPicture.getWidth(null),myPicture.getHeight(null));

Now use this JLabel piclabel

简单方法：您可以将图像文件夹设置为classpath并通过eclipse导出jar文件。
