CoClasses and Classes Description
ImageServerLayer Image server layer source and display options.
[C#]

This example shows how to create an image server layer from a URL, clip a portion of image and save it to a file.

public static void AccessImageServerLayer()
{
  //create an image server layer by passing an URL
  IImageServerLayer2 imageserverlayer = new ImageServerLayerClass();
  string URL = "http://myserver/arcgis/services/amazon/imageserver";
  imageserverlayer.Initialize(URL);

  //get raster from the image server layer
  IRaster raster = imageserverlayer.Raster;

  //raster from image server is normally large, you need to
  //define the size of the raster
  IRasterProps rasterProps = (IRasterProps)raster;
  IEnvelope clipEnvelope = new EnvelopeClass();
  clipEnvelope.PutCoords(779000, 9628000, 786000, 9634000);
  rasterProps.Extent = clipEnvelope;
  rasterProps.Width = 256;
  rasterProps.Height = 256;

  //save the clipped raster to File Geodatabase
  ISaveAs saveas = (ISaveAs)raster;
  IWorkspaceFactory workspaceFact = new FileGDBWorkspaceFactoryClass();
  IWorkspace workspace = workspaceFact.OpenFromFile("c:\temp\fgdb.gdb",0);
  saveas.SaveAs("clipfromimageserverlayer", workspace, "gdb");
