How to I create images in Illustrator or Photoshop to put in Flash that won't make the file size huge?

Question

I have Flash CS3, Illustrator, and Photoshop. I find it much easier to create in Ill. or P.Shop and import those images into Flash. However, my first test movie was so far only like 30 seconds long, but already 2+MB in size. I've seen 10min movies that are only like 6-7MB total. Is there a way to make the import files smaller in size in the end? Any suggestions would help. :)

PNG24 if you want quality, transparency support and small size.
PNG lossless compression algorithms reduce file size with no loss in image quality while JPEGs lose quality every time they are opened and saved.
But if you need an even smaller size, well, only GIF remains.
