This, partly, and "security concerns" also inspired my "implement with changes". I don't know exactly what the security concerns are, either, only that there might be ways in through the pics themselves, possibly - or maybe not - ... and just out of curiosity, if s.dreamwidth.org is not serving icons (which I thought it was) then what exactly is it serving? It's by far the slowest loading sub-domain on Dreamwidth (to the point that I'm tempted to block it on days I'm on a slow connection just to load pages more quickly).
