I suppose that someone knows because I saw one today and it was the first time I’ve really noticed one and thought about it. So for today’s Wednesday Whim I decided to add one for the Knetwork. All you need is an animated gif, scaled down to the recommended 16×16 pixel size, uploaded to your existing favicon location. Then add a html line to your header. Just copy your current favicon code, paste it below itself, and alter the file name to your animated gif.
FYI – mine is a little knight hacking away at something…. it’s probably dead by now. I’ll probably replace it or remove it but lemme know what you think!
