[closed] KML/KMZ Super Overlays

Some large raster maps are tiled and available as KML super overlays, Does AQ support these?
One such file I tried to import, all I get is: ! Import ERROR: 0 Item
https://environment.data.gov.uk/image/r ... pImage.kmz
from :
https://environment.data.gov.uk/image/r ... mageServer
Loads in QGIS and Google Earth
Just want to download the tiles in view or select and save an area.

Hi,
If the data is not contained in the KMZ file, then you won't be able to open it.
But the application does support
ImageServers.
Note you can import 1m DTM from a pre-made file available here:

The layer I am after is the Hillshade version of the DTM which unfortunately is not available via WMS
I've had a play with trying to get the imagery to load with an AQX file, which sort of works, but AQ doesn't seem to save any of the imagery
select+save or zooming in and out = " Failed to write data: IOEXCEPTION (write failed: (I/O error)) "
I don't really know what I'm doing but it sort of works... well some tiles load in a clunky fashion. Any help to improve this?
