Optimization, Done the Right Way
I just used this technique from Smashing Magazine for a few of my websites. I build my sites with WordPress and have been hearing from my clients that the sites were slow. Granted, these are graphic rich sites, but in this day and age with high bandwidth, that shouldn’t really matter, right? Wrong! I tried so many tips and tricks and this technique (posterizing the images) worked masterfully. On some images, I crunched more than half the size out.
To put a number to this, I eliminated over 130k in some instances on a restaurant site where image presentation is key. I posterized, reduced, masked where I could not suffer in quality and tadaaaaa! This is a great tut, one definitely worth saving and referencing over and over.
