14   * <LI>src: A static URL for the image source.</li>
15   * <li>data: A NSData object with the image content. Must be used with mimeType.</li>

17   * <li>filename: The path to a file containing an image.</li>
18   * <li>framework: The framework where the image should be retrieved from (used in conjunction with filename).</li>
