Optimizing the images of a web page is easy and the best way to speedup the site. On the basis of the famous book “Even Faster Web Sites” by Steve Souders, Annette Landmesser and I made a small presentation for an university course called Development of Rich Media Systems thought by Jakob Schröter. The presentation contains some general patterns and practices for lossy and non-lossy optimization. Enjoy.
I will also write a paper about image optimization for websites for my university course in a couple of weeks. The paper will be in German.
Best regards, Thomas Uhrig
