Because some of you complained about the byte size of my homepage http://mediabeez.ws (was 2.5mb due to artwork), I've invested some time in shaving off quite a few bytes; I've discovered that by using photoshop to reduce the animation image color depth to "indexed color, 217 color", I can get the animation image file size down to less than 50% of the original that was output by my spriteGenerator-1.0.0 And you hardly notice the difference at all :) I'm going to update http://mediabeez.ws later today, hopefully after I find a way to do this with imagemagick, which my spriteGenerator uses. And since I also use half the frames for my site logo of http://mediabeez.ws, that animation file is now 297kb, down from 2mb.
