QGIS doesn't support most ArcGIS Image services, it can and will only request 
the base image. In your case not even that. The plugin you've mentioned is 
sadly no longer updated and won't work with recent QGIS and modern Python. You 
can try to make it work with QGIS 3.6, process the data and later continue 
your project in QGIS 3.36 or 3.40.

There are multiple bug reports on ArcGIS REST services:

A quote from Nyall Dawson, one of the core QGIS developers in the above 
thread:

So, tl,dr: you need to get some funding to pay a QGIS developer to implement 
these missing features. You can skim through this mailing list, stackexchange 
and the bugreports to find other users that are affected. Maybe you can 
scratch up some funds together. And always think about, how much money you're 
already saving by not subscribing to ESRI!
