Arcgis online - Popups on imagery layer not working - No information available

[MariusHelsem]

I have published an imagery layer with a raster mosaic, and wish the pixel value of a location to display when clicking the raster in a web map. However, when I enable the popups for the layer, "No information available" is displayed in the popup window. 

Any known list of reasons why this might be? 

Thanks

Marius,

The short answer is that this cannot be done. Please see this support article for information on why and for workarounds:
