Map Image Labeling

[GaryMorris]

I have a map image layer that is shared through our portal.  I added it to an ArcGISOnline map; when I try to adjust the labeling extent of one of the layers, the labels disappear.  The labels are still turned on but they are not displaying anymore.  If I add the map image layer again, the labels work until I try to adjust the labels and again they disappear.  

Any help in solving this would be greatly appreciated.

Try adding it to AGOL by index eg. mydomain/arcgis/services/rest/MyLayers/11, which should add it as a pseudo feature layer and then retry.

Thank you for the response, can you expand upon this.  I have never added a layer that way.

When working with a map image layer (adding it by URL at the MapServer endpoint) will have the labels returned by the map image layer as an image from the service to map viewer. There might be something you are configuring on the map image layer that is failing to return from the service. If you add the layer by the specific layer like MapServer/1 this will handle the map image layer as a feature layer and the labels are no longer returned by the service but are handled my client app which in this case would be Map Viewer.
