And now I was curious and played with their site. Optipng cut 20% off the iphone.png (originally 37 Kilobytes). But by simply using JPEG you get a file of just about 10 Kilobytes. If you want to go even further you could combine the images per row (eg http://www.serverdensity.com/img/screenshots/viewserver-small.png http://www.serverdensity.com/img/screenshots/viewserver-smal... and http://www.serverdensity.com/img/screenshots/serversnapshot-small.png http://www.serverdensity.com/img/screenshots/serversnapshot-...) and use an image map for the links. PS: You are scaling those images in the browser. That looks incredibly bad, don't do that! Very noticable on the terminal shot. ;-)
