Would you mind telling your variations?

Not at all. In fact, I'm glad you asked. I was tempted to
post it in my reply, but the changes were so trivial I thought
best not at the time.

import javax.imageio.ImageIO;
import java.nio.ByteBuffer;
import java.nio.channels.FileChannel;
import java.awt.Image;
import java.awt.image.RenderedImage;

import javax.swing.JOptionPane;
import javax.swing.JLabel;
import javax.swing.ImageIcon;

public class ImageLoader
  public static void main(String[] args)
    for (String s : ImageIO.getReaderFormatNames())
      String path;
      if (args.length==0)
        path = JOptionPane
            "Image Path",
        path = args[0];
      FileInputStream in =
        new FileInputStream(path);
      FileChannel channel = in.getChannel();
      ByteBuffer buffer =
      Image image = load(buffer.array());

      System.out.println("image: " + path + "\n" + image);
        new JLabel(
        new ImageIcon( image )) );
    catch (FileNotFoundException e)
    catch (IOException e)

  static Image load(byte[] data)
    Image image = null;
      SeekableStream stream =
        new ByteArraySeekableStream(data);
      String[] names =
      ImageDecoder dec =
      RenderedImage im =
      image =
    catch (Exception e)
    return image;

You'll have to forgive my failure to wrap those calls
to Swing methods in a Runnable, (shrugs) or perhaps
not. In any case, I am confident you are capable of
doing that yourself, and I wanted to post the code
*exactly* as I'd seen it work.

Oh, and if I was going to take it beyond 'absolutely trivial'
changes, I would probably swap that first input dialog for
a JFileChooser.

I swiped the code (with slight variations) from the
JAI-Demo project -
The source can be viewed here:

Cool. Thanks to 'aastha' for the original code, and you
for the alterations and link. That was actually the first
time I'd played with JAI, your post 'inspired me'. :-)
