How do you make a saturation changing gif file?

I have a photograph that I want to turn into a 6 second color changing gif file some similar to this http://media.photobucket.com/user/MANITOU57/media/MARIJUANA%20ANIMATIO NS/ANIMATIONICONATOR2.gif.html?filters[term]=pot%20leaf%20gif&filters[ primary]=images&sort=1&o=29 but in my case not a pot leaf. i want to know how i would go about starting this any insight would be highly appreciated... I have CS^ as i forgot to mention.
