Can I make an image in photoshop and then put it into my flash movie? If I cant, then what if for example I had a logo that I used for everything, and I needed to use it in my flash movie, what could I do?
The only advantage to using Fireworks instead of Photoshop in this instance is that it'll preserve alphas and things in graphics you've created if the information is saved in the MM PNG format. If you're importing, say, a family photo though it'll make NO difference whatsoever!
(Fireworks makes a better job of vector than Photoshop though.)
