Displays an image read from a URL within a JFrame. urlLocation URL pointing to an image.

public class ShowImageFromURL {

    public static void show(String urlLocation) {
        Image image = null;
        try {
            URL url = new URL(urlLocation);
            URLConnection conn = url.openConnection();
            conn.setRequestProperty("User-Agent", "Mozilla/5.0");

            conn.connect();
            InputStream urlStream = conn.getInputStream();
            image = ImageIO.read(urlStream);

            JFrame frame = new JFrame();
            JLabel lblimage = new JLabel(new ImageIcon(image));
            frame.getContentPane().add(lblimage, BorderLayout.CENTER);
            frame.setSize(image.getWidth(null) + 50, image.getHeight(null) + 50);
            frame.setVisible(true);

        } catch (IOException e) {
            System.out.println("Something went wrong, sorry:" + e.toString());
            e.printStackTrace();
        }
    }
}
