//  File:		NamedImagesCollection.cs
//
//  Namespace:	System.Windows.Forms.DataVisualization.Charting.ChartTypes
//
//	Classes:	NamedImagesCollection, NamedImage
//
//  Purpose:	Every property in the chart references images by names. 
//              This means that you can set MarkerImage property to a 
//              full image path or URL. In case when the user wants to 
//              dynamically generate an image or load it from other 
//              location (like database) you can use named image 
//              collection which is exposed as Images property of the 
//              chart. Any Image can be added to this collection with 
//              unique name and than this name can be used in all the 
//              chart properties which require image names.
