External images not smooth in BitmapImage as3

What I'm doing

Hello Im having problems loading external images into my flash (builder) application. To show the image I use a BitmapImage with smoothing enabled like this:

<s:BitmapImage id="image" smooth="true" smoothingQuality="high" width="100%" height="100%" fillMode="clip" />

I also show thumbnails using the new flex4.6 scaleMode ZOOM like this:

<s:Image id="thumbnail" scaleMode="zoom" smooth="true" smoothingQuality="default" />

I preload the external image using a SWFLoader because I need to store the original image width and height

The problem

When I test my application locally everything works fine! But when I run it from my web domain I see its showing problems. For images running on the same domain and images from Flickr = no problem. But other images like from imageshack show the following problems:

Cause?

Im not really sure whats causing the problem, but the only difference I see in the image sources is in the domain policy. The crossdomain.xml for Flickr allows all http://farm1.static.flickr.com/crossdomain.xml unlike imageshack.us http://www.imageshack.us/crossdomain.xml

If this would be the cause then I dont understand why the image is still being loaded but crappy. Does anybody know what's going on exactly? Any solutions? Thnx.

There are certain limitation to loading images cross domain without the correct policy enabled. Flash will load the data, but not allow any manipulation, including smoothing.

There are a number of ways around this. You could use a server-side proxy, loading the image via a local php or asp page. It's not the fastest solution, but it will work.

You could also try loading the image with LoadBytes, then passing the byte-array into a Loader object. It's not as pretty as using the Flex component, but it should restore some control to you.
