Great article about using concatenation of images. I have been doing this for a while. For me, a major trick is to make sure that the images still look good even though they might be of varying colors. I have been considering one giant “icons” image that has all of them. I worry about the maintenance and management and the image optimization.
I wonder, why isn’t there animated PNG’s? I have been waiting for PNG to become the standard image of the web for a long time. IE7 has support, and IE6 has some hacks that give limited support. But do these work if the background image is a PNG? I wonder if the concatentation technique will work with PNG’s. Will the PNG files look better at lower file size? I should do some experiments with this.
Random other news: Adobe announced that they are going to OpenSource Flex. I think this is a good move. Even though I hate Adobe right now. Maybe if there was a free way to make rich apps, it would help them.
Whatya think?
