Twisting images animation please help

I am designing a website for the club i dj at and the boss wants to have images that are on for 5 or 10 seconds then twist and transform to another image but i dont have any idea on how to do this.

Im using flash mx 2004 professional and need help on how to do this please could you lot help out.

If I cant do it with flash what software do I use and are they free.

I would look up "tweening" in the flash manual -- probably get you well on your way
