How do I make my flash game keep picture quality when browser resized

How do I make my flash game keep picture quality when browser is resized.
I built a flash game combining using actionscript and whenever the player or browser is resized it loses quality. This really annoys me...
Is there a way so, if the browser for example is made smaller the game's picture still keeps its display quality

If you can help plz do. Thanks
