I'm not entirely sure of your question, but my guess is that you are
trying to do something like what a web browser does? i.e. download an
.html file which has URL references to various image files?
If that is correct, then you need to make multiple requests via
IDLnetURL. Get the .html file via IDLnetURL, parse the HTML file to find
the img tags, and then download the associated images.
