it isnt that hard, just take all your images, and give them a differnt keyframe on the timeline up at the top. the longer the space between keyframes, the longer it takes to hit it, so space them as you want.
i would do as they said and make a movie clip object and do it in that, then you can drag that by opening your library (Ctr-L) and dragging it onto your scene. then you can add your own Titles and such at the start.

i would do flash too. you can add your own stuffs too it (like i said, titles and whatnot), then you can also put them on websites and people dont have to download them, flash files are better for animated movies, imo. otherwise i would make a true video file.
