This property is only applicable when the control's Expanded property is set to false.
When the control is collapsed, tiles are rendered at a considerably smaller size than when it is expanded. An image that is appropriately sized for the expanded state might not appear correctly at this smaller size; this property provides a way for the developer to specify a different image to be displayed when the tile is drawn at this smaller size.
Note: Collapsed tiles are rendered at the same size for all screen resolutions, which is equal to one-fifth the value of the TileSizeSmall property for the 'Scale100Percent' screen resolution setting.
