VisibleLayers is defined by a combination of layer visibility in the TOC (i.e. is the layer "on"?) and layer visibility dependent on map scale. Scale dependency for a layer is set in the original map document. If the layer is scale dependent (i.e. a maximum and/or minimum scale has been set) and the map scale falls out of this range, layer visibility will be false. Do not confuse this property with the visibility property on ILayerDescription which is based solely on layer visibility in the TOC (is the layer "on" or "off"). The IMapImage interface inherits all IImageResult properties.
