This example demonstrate how to load image file as InputStream:

        VBox rootBox = new VBox();
        rootBox.getChildren().addAll(btnLoad, label, myImageView);
        
        Scene scene = new Scene(rootBox, 300, 300);
        
        primaryStage.setTitle("java-buddy.blogspot.com");
        primaryStage.setScene(scene);
        primaryStage.show();

    public static void main(String[] args) {
        launch(args);
    }
    
    EventHandler<ActionEvent> btnLoadEventListener
    = new EventHandler<ActionEvent>(){

        @Override
        public void handle(ActionEvent t) {
            FileChooser fileChooser = new FileChooser();
            
            //Set extension filter
            FileChooser.ExtensionFilter extFilterJPG = new FileChooser.ExtensionFilter("JPG files (*.jpg)", "*.JPG");
            FileChooser.ExtensionFilter extFilterPNG = new FileChooser.ExtensionFilter("PNG files (*.png)", "*.PNG");
            fileChooser.getExtensionFilters().addAll(extFilterJPG, extFilterPNG);
             
            //Show open file dialog
            File file = fileChooser.showOpenDialog(null);
            
            String path = file.getAbsolutePath();
            label.setText(path);
            
            try {
                InputStream inputStream = new FileInputStream(path);
                Image image = new Image(inputStream);
                myImageView.setImage(image);
            } catch (FileNotFoundException ex) {
                Logger.getLogger(JavaFXPixel.class.getName()).log(Level.SEVERE, null, ex);
            }

        }
    };
}

Compare with Using ImageIO.read(file).
