Ah, but you see, I have a caching proxy! Squid. My netscape cache's
the images (ie, writes them to disk) but they are overwritten
everytime. Since I connect via modem, I can watch them repopulate
Even if Netscape does hold on to them without a caching proxy, we
couldn't rely on that behavior.
This problem makes 'icon' an undesireable object to use.
