	public String getImageFolder() {
		return "D:/upload";
	}

	public void onOk() {
		if (getFile().getFileName().length() == 0) {
			return;
		}
		byte imageData[] = new byte[(int) getFile().getSize()];
		InputStream fileInput = getFile().getStream();
		try {
			fileInput.read(imageData);
		} catch (IOException e) {
			throw new RuntimeException(e);
		}
