fullscreen scale image proportionally

I'm really close to make a "fullscreen scale image proportionally". Now i know how scale image proporcionally to width, or height. I don't know how i can combine this two scales. For explane first script is for scale width:

Code:

---

sky.height = (stage_width / old_width)*old_height;
sky.scaleX = stage_width / old_width;

---

And this is for scale height:

Code:

---

sky.width = (stage_height / old_height)*old_width;
sky.scaleY = stage_height / old_height;

---

I wonna do something like this:

Code:

---

function() {
if (stage_width > stage_height) {
sky.height = (stage_width / old_width)*old_height;
sky.scaleX = stage_width / old_width;
}
else if (stage_width < stage_height) {
sky.width = (stage_height / old_height)*old_width;
sky.scaleY = stage_height / old_height;
}
}

---

Idea is really simple. If my web broswer have more width like height, then flash web site use first script. Else use secund script. But i'm not a programmer, so i don't know how i can make this :/

@ 3DH: This is awesome! Just what I've been looking for. Can you please post the entire code (or even the .fla file)?

Me too, i think it looks fine.
The only glitch i saw was when you actually go beyond (what i believe to be) the real size of the image. I mean when you make the image smaller and you go smaller than the real size it seems to jump back out to the real size after a certain limit.

apart from that i think its pretty cool.
