You need to explicitly allow cross-domain access by creating a crossdomain.xml file in your root folder.

<?xml version="1.0" encoding="utf-8"?>
    <cross-domain-policy>
        <allow-access-from domain="*" />
    </cross-domain-policy>
    ...

The site you are loading images from has to explicitly grant Flash/Flex applications by hosting a cross-domain.xml file.

You need to have a crossdomain.xml file. After that you need to explicitly load that crossdomain file using the code:

Security.loadPolicyFile("http://foo.com/crossdomain.xml");
