As well as being used as photo manipulation software, Photoshop is also the standard in the creation of websites, logos and other web based images. This makes it the perfect compliment for Flash as it allows you to import nicely designed logos and backgrounds, allowing the quality of your Flash to be improved ten fold!
OK, we're ready to import some Illustrator content directly into Flash. You'll see that when you do this, Flash will present you with a dialog similar to the one you saw when importing Photoshop files, which includes a pile of options to make the whole process nice 'n easy - and they let you do some pretty powerful things too, like preserve layer editability and so on.
