* <code>ImageItemExecutor</code> is a concrete subclass of
 * <code>StyledItemExecutor</code> that manipulate different types of images.
 * An image can be represented in a design file in one of the following forms:
 * 
 * <li>
 * <h4>URL</h4>
 * <ul>
 * The identifier for the image if the type is File or URL. The type of image is
 * inferred from the image file content or HTTP response.
 * </ul>
 * <li>
 * <h4>Embedded</h4>
 * <ul>
 * The image is embedded in the design file. The <code>ImageItemExecutor</code>
 * gets the binary data of the image content (DE is responsible for decoding
 * BASE64 image content), and saves it to a temporary file before forwarding to
 * the corresponding emitter.
 * </ul>
 * <li>
 * <h4>Database</h4>
 * <ul>
 * The image comes from a BLOB field in the query. It also required to save the
 * image content to a temporary file.
 * </ul>
