Flash movie - high res verison, low res version, changing bitmaps automatically?

[avar]

I'm creating a flash movie that will run on both the web and, separately, run on an HD screen. Both versions are identical, except that the web version should use low-res bitmaps, and the HD version should use high-res equivalents of those same bitmaps.

Manually replacing and resizing each bitmap for the entire movie will be very time consuming and error-prone; does anyone know of a way to automatically swap the high res versions somehow?

[whispers]

you could load the images dynamically then all you'd have to do it is replace the folder of images with low or hi res versions..

also in the library you can click on properties and update/swap out to a high res version.
