how do you do complicated masks in flash

[nicolaszein]

i see a ton of great sites that have complicated images involved but it seems like it would take too much time to do in flash, so how is it done, with an imported path from photoshop, another macromedia application, some mysterious trick?

thanks for the help.

If you give an example I could try and explain for you as I dont quite understand you at the moment.
