Shows the most interesting photo for a given date (in the past) from the Flickr Interestingness photo collection. This is a specialized class of CalendarDay used by FlickrInterestingNavigator to show interesting photos by month.

Note: By default, a FlickrInterestingDay control will not load a photo. You must either set its autoLoad() property to true, or manually invoke the control's loadPhoto() function, for the control to load its photo.
