/**
 * WOImageButton renders a dynamically generated IMG tag or an INPUT tag, depending on whether the
 * element is inside a WOForm (in which case an INPUT of type IMAGE is generated) or not (in which
 * case the equivalent of a WOActiveImage)
 *
 * Bindings are:
 * <UL>
 * <LI>src: A static URL for the image source.</li>
 * <li>data: A NSData object with the image content. Must be used with mimeType.</li>
 * <li>mimeType: The MIME type for the image data. Can be used with filename or data bindings.</li>
 * <li>filename: The path to a file containing an image.</li>
 * <li>framework: The framework where the image should be retrieved from (used in conjunction with filename).</li>
