The guys over at Meet The Gimp did a nice little article [Episode 155:] Favicon] about how to create a Favicon image with the GIMP. - You might want to check it out, as it relates to my other post about FAVICON.ico files. :)
PS. I hope everyone had fun at the Indiana Linux Fest this weekend... I forgot to mention it in a recent episode of the Juiced Penguin... Doh!
