Photoshop or illustrator are pretty powerful programs that can really create stunning images. Only problem is that it is expensive. However, you can try it free for 30 days though.
Additionally, I know that -at least with Ill- you can easily copy/paste between Illustrator and Flash, not even requiring you to save. Probably because it's also a vector-based program, and also made by Adobe
