Raster and grid images can be included in a named map that can be rendered via the Mapping Service or queried for its metadata via the Feature Service. This is done by creating a named layer or named table for the raster or grid, just as you would do for a vector layer.
The overall process of using raster and grid images in Spectrum Technology Platform is to create the image as a named table or named layer and include it in a named map definition.
Use either SOAP or REST to render the map or retrieve metadata about the image.
