Right, but you are still having to download the entire image file and
just sizing it right? What I was wondering if it is possible to only
donwload part of the image file like a segment, or a very low quality
to save the user bandwidth. Is that possible with AS3 on the fly, or
would I have to use something like imagemagik for that?

Definitely possible -- I do it using a function like so:
public function getBitmapData(target:UIComponent, scale:Number =
0.):BitmapData
{
var bd:BitmapData = new BitmapData(target.width * scale,
target.height * scale);
var m:Matrix = new Matrix();
m.scale(scale, scale);
bd.draw(target, m);
return bd;
}
Basically what that function does, it accepts a target UIComponent to
draw the thumbnail from (in my case it's usually charts, but to do
what you're after you might use an Image or an SWFLoader). It also
accepts a scale to upsize/downsize the bitmap to... by default it does
it 1/3 of the size.
Cheers,

shrinking the size. Anyone know if that is possible or any
alternative methods I could possibly use for this?
