Like I was telling EC, wherever I am, the internet connection tends to be rather good. There is no need to cache much of anything. When the cache grows too large, the browser will lag longer, trying to decide whether it has seen the image before or not, than it would have taken to go ahead and download and display the image again.
The caching was implemented during a time when 80 or 90 percent of internet users were still using dialup.
