  BufferedImage img = null;

   img = ImageIO.read(new File("block.png"));

   e.printStackTrace();
  }
  
  JLabel picLabel = new JLabel(new ImageIcon( img ));
  mainFrame.add(picLabel);
  
  mainFrame.setVisible(true);
 }
}

I have file named "Squared.java" and an image called "block.png" in the same folder and in the same package (using Eclipse); I get this:

Code: [Select]

javax.imageio.IIOException: Can't read input file!
Why can't it get the file, it's in the same directory. Thanks

Is it in the same directory that you are searching in, though? There is a method to get the full path of a file object. Use that instead of trying to read the picture file, and it will tell you where it is looking for it.

You need to place the image files in the source root. So, if your source (relative to the Eclipse project) is src/mypackage/Squared/<files>, you need to put the image under the src folder. Then, in the code, use this to get the URL of the resource

Code: [Select]

this.getClass().getResource("filename");

file:/home/david/Documents/Java/Squared/bin/block.png

Thanks a lot Graphmastur and Binder News. I get now, the image has to be in the folder where the class file is, thanks
