[IDV #CUC-588449]: load satellite image with ISL from ADDE server

Hi David.

The problem is that the scriptability of the ISL is fairly limited, as far as I 
can tell. In your use case you are requiring greater programmatic control which 
I am not sure the ISL can offer you.

You may also want to take a look a Jython support within the IDV. Jython is a 
complete programming language that will allow for the sort programability that 
you may be looking for.
