/// watermark functionality is enabled. This option should only be used when it is not important to restrict access to
/// the media objects.

/// <exception cref="GalleryServerPro.Events.CustomExceptions.BusinessException">Thrown when the current media object's

/// <remarks>Typically this parameter is used instead of {MediaObjectAbsoluteUrlNoHandler} when the media objects directory
/// is outside of the web application. If the user wants to allow direct access to the media objects using this parameter,
/// she must first configure the media objects directory as a virtual directory in IIS. Then the path to this virtual directory
/// must be manually entered into one or more HTML templates, so that it prepends the relative url returned from this method.</remarks>
/// <example>If the media objects directory has been set to D:\media and a virtual directory named gallery has been configured
/// in IIS that is accessible via http://yoursite.com/gallery, then you can configure the HTML template like this:
