 final URL url = cls.getResource(imageName);
 if (url == null) {
 return null;
 Image image = (Image) imageCache.get(url.toString());
 if (image == null) {
 image = Toolkit.getDefaultToolkit().createImage(url);
...

BufferedImage loadFromURL(String url)
load From URL

try {
 return ImageIO.read(new URL(url));
} catch (IOException e) {
 e.printStackTrace();
return null;

BufferedImage loadImage(byte[] data)
load Image

BufferedImage img = null;
try (InputStream input = new ByteArrayInputStream(data)) {
 img = ImageIO.read(input);
return img;

BufferedImage loadImage(File pFile)
load Image

BufferedImage im = ImageIO.read(pFile);
GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice device = env.getDefaultScreenDevice();
GraphicsConfiguration config = device.getDefaultConfiguration();
BufferedImage buffy = config.createCompatibleImage(im.getWidth(), im.getHeight(), im.getTransparency());
Graphics2D g2d = buffy.createGraphics();
setupGraphics(g2d);
g2d.drawImage(im, 0, 0, null);
...

BufferedImage loadImage(final byte[] imageData)
Uses javax.imageio.ImageIO to read the specified data into a java.awt.image.BuffededImage.

final ByteArrayInputStream in = new ByteArrayInputStream(imageData);
final BufferedImage bi = ImageIO.read(in);
in.close();
return bi;
