Image services are started from ArcCatalog (not from an MXD), so I cannot set the limit the draw scale in the layer properties in the MXD.
I tried modifying the cache properties but the service still draws at all scales. (See attached service properties dialogue box.) I set the max scale to 1:16k but the service still draws at 1:8k and 1:2k (I assume it is drawing them dynamically).
Seems to me this should be a simple thing to adjust, so not sure what I am missing here! Thanks!
