I made mine on my other site - Just like Yahoo's.
Its just a big "E". Anyway, the way I did it was, I believe, I created my "E" in Photoshop than copy/pasted to a program which saves images as: ".ico". Then added the code above by
BoRiCuA and the image to server.
I dont have It on my computer anymore - but just do a google search on it. It was free.
