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?
