This should get you started ... 

var dispatcher = Dispatcher.CurrentDispatcher;
var loadTask = new Task( () =>
    {
        Image image = YourMethodThatLoadsImagesFromFB();
        if ( dispatcher.CheckAccess() )
        {
            YourMethodWhichProcessesReceivedImages( image );
        }
        else
        {
            dispatcher.BeginInvoke( YourMethodWhichProcessesReceivedImages, image);
        }
    } );
loadTask.Start();
