Convert BufferedImage to ImageIcon

File img = new File("C:\\..\\image.jpg");
BufferedImage bufferedImage = ImageIO.read(img);
ImageIcon imageIcon = new ImageIcon(bufferedImage);

BufferedImage extends Image, so it's simply:

new ImageIcon(myBufferedImage);

your bufferimage;
JLabel photo = new JLabel("Photo");
photo.setIcon(new ImageIcon(bufferimage));

Use constructor: ImageIcon(Image image), BufferedImage extends Image.
