macromedia flash sitedesign : PLEASE HELP WITH SIZE/PIXELATION ISSUE

As it says in the summary i need help customizing my animation to screen
resolutions avoiding pixelating.
I have created high resolution images which i want to turn into animations and
having exported the images as PNG files (to maintain their transperancies), i
have found that unless i set the movie publish setting to "match movie", flash
essentially destroys the quality in its resizing.
I can't understand why flash would'nt have a similar programming situation to
the image development programs that keep an image's quality no matter how you
scale it.
There does not appear to be any setting within flash that can do this and it
seems to me that the only way to get a perfect result is to literally export
every image i create to a specific screen size, but in doing so i realize that
any change in screen resolution will mess the image up again leaving me at a
complete loss of how to deliver the animation effectivey.
I want (and have in the past used) the "percentage" variable for the
animations but the pixelation issues i'm having now are unacceptable.
I am thinking this may be a problem specific with PNG files but i don't know..
PLEASE HELP!!!!!!!!!!


Thanks

Although Flash itself is a vector based program like Illustrator and allows for
wonderful scaling of drawn art like lines and text, there is really nothing
Flash can do to help the fact that a Bitmap image (JPEG/PNG/GIF) is going to
pixelate when upsized. A Bitmap is sadly limited by the number of pixels
present in the image. If you want to resize these images up during animation,
you're going to need to export them as their maximum size from Photoshop or
whatever program and then scale them down with the IDE or Actionscript.

Scaling a raster image in any application will cause some quality degredation.
It's the nature of raster images. Photoshop can interpolate images up but there
is still a loss of quality. I have not been able to use larger images, reduce
them and have them look great in Flash either.

I have gotten around this in the past by creating two images... one at
original size and one as it would appear blown up and essentially cropped to
the stage area (to keep file size as small as possible). During the scale
tween, the original image fades out as it enlarges. At the same time the larger
image (reduced at the beginning of the tween) fades in. It appears that the
smaller image starts out looking great and enlarges without any loss in quality.

Thanks SymTsb and aniebel ...
Neither answers really address the issue.... I am not actually scaling
anything at all and the issue seems to be completely related to the function of
having it maximized within a window...
The only solution it seems to perfect quality is using "match movie" when
setting publish but that leaves the annoying fact of having to set definate
size boundaries which will variate quality on different resolutions......
Thanks though..
