you want RR to go FETCH and download that image...
I cant say that would be something we would do
but still the idea of going to the cloud to get an image, isn't a good one
specially in a list that has to move, the image has to be there, no time to fetch
prefetch, yea.. that would mean when you load the list, each one would have to be fetched
that would be a time thing, assuming high speed net connection too
I assume webclients check cache, but I don't know
