Improve Image Quality on Bitmap movement

http://yngbldjr.brinkster.net/index2.html

I am having trouble with image quality in my site… I have a bunch of images that are cut out… resized… and imported into flash… I want to have better/smotther movement from the images. I have tried several things…

I have tried to put all the images into their own movie clips (got worse results) Dont know what else to try

I am also a noob to Flash (working in it for 8 months or so…my background is coding… so I can handle all the actionscript… but I suck with images…)

I have tried to use both Fireworks and Photoshop to produce the PNG’s, but got the same results.

here is the site…
