This method allows you to quickly add an item from a RasterImage. It is the equivalent of the following code:

ImageViewerItem item = new ImageViewerItem(); 
item.Image = rasterImage; 
item.PageNumber = pageNumber; 
imageViewer.Items.Add(item); 

If rasterImage is null, then an empty item is added.
