I prize your sense o humor, calling JPEG "the most optimized lossy compression format", as it can be further compressed losslessly another 23...24%.

Indeed, which is why I said the most optimized lossy format, any format can losslessly be compressed more, but it's a matter of CPU utilization required to achieve that both on the compression end, and the decompression end. CPU utilization during browser rendering is not something to ignore, and lossless compression techniques that can be tacked on only add to this, not to mention the diminishing returns it takes to compress the file that much. It takes considerably more processing power to compress an image more and more as the low hanging fruit of the binary level compression gets taken. Technically you can tell your browser to do gzip compression right now for images, but it will actually slow down your overall page display time (from my testing) for the little bit of download size it saves. I'm know there are better lossless compression techniques that can be used other than those used by gzip, but I still doubt the tradeoff is worth it, and those would require a new format adoption as mentioned, not an easy task ;-)
