Happy Halloween! On a sidenote: I downloaded a screensaver at inkymole. I love it. I really love her stuff!
So, I think this probably works on firefox alone, however my friend said it might work in Internet Explorer. I will check when I get home.
I decided to create an animated favicon. You know, those cute icons that appear in the browser address bar. Mine animates. It looks like the image on the left. If you go to my portfolio domain: jerlyn thomas. It should work if you are using firefox at least. So, how do you do it?
First off in the html code you want to include this in your header.
<link rel=“icon” type=“image/gif” href=“./favico.gif” />
I named mine favico.gif however I read that you can rename it to .ico and it should be fine.
It does not animate in other browsers so I suggest leaving it at a default first frame. For example, mine looks like this in safari. 
Well, good luck, let me see how yours turn out.
