Raster = Faster performance, but large file size.
Vector = Slower performance, but smaller file size.
That’s the basic idea. Of course, there are acceptions to that rule.
So for your project it sounds like raster images are the way to go (JPG, PNG , GIF). I would suggest PNGs for all Flash images. They support alpha, and you can apply jpg-like compression to them through Flash.
Just remember, you won’t have much luck resizing your raster images later.
You can also load both raster and vector graphics from external locations, which means quicker (main animation) download times.
