                Facebook.api("/me",getMeHandler);
                userImg.source=Facebook.getImageUrl(success.uid,"small");
                Facebook.api("/me/statuses",getStatusHandler);
            } 
        }
        protected function login():void
        {
            Facebook.login(loginHandler,  {perms:"user_birthday,read_stream,publish_stream"});

        }

The image is stored on the public server.Can anyone point me where I am goin wrong???

Solution

i'm not really sure about this line:

Facebook.login(loginHandler,  {perms:"user_birthday,read_stream,publish_stream"});

on air i'm using:

Facebook.login(loginHandler, ['email', 'user_birthday', 'read_stream', 'publish_stream']);

when you are allowing application to use your data, do you see it like this?

enter image description here

UPDATE

try it like this:

private function submitPost():void {
        var params:Object =
        {
            message:'My test post of the image',
            picture:'http://actual.path.to.the.jpg',
            link:'',
            name:'',
            caption:'',
            description:'description about image',
            source:'';
        };

        FacebookDesktop.api('/me/feed', submitPostHandler, params, "POST");            
    };
