Yeh, I understand that PNG is not lossy and JPEG isn't. I just thought 
there might be some trickery like saving a lossy JPEG out as a PNG? I 
used to use Macromedia Fireworks back in the day and it was a lot better 
at compressing PNGs pretty small without too poor a quality hit but they 
do crazy stuff with PNGs too like adding in vector support.

I will definitely give optipng a try but I don't have much hope of 
getting it down to 7k like in the jpg. :( I did indeed reduce the bit 
depth as well.
