Remarks

The Download method return an ImageServerDownloadResults which contains multiple ImageServerDownloadResult objects, and each one of them contain a downloadable file and its size in bytes.

The number of items that can be downloaded is defined in the image service
configuration. One item might be corresponding to multiple files. For example a raster of a pan-sharpened image service consists of a single band raster dataset and a multiple band raster dataset, where each dataset might consist of multiple files such as an image file, a world file, and a pyramid file.The returned downloadable files can be URLs (e.g. http:// or ftp://) that are directly downloadable from a remote server. They can also be files that are known only to the image service. In this case, GetFile() should be used to prepare the file for download and get a public URL.

Downloading formats of folder structure, for example ESRI GRID, is not supported.
