    hi,

    u can use promise which will handle async operations as below:

    WinJS.xhr({url:"webservice url"}).then(

    function onComplete(){

    image.style.hidden

    };

    function onError(){

    };

    )

    //show ur loading images here:

     image.style.visible

    Hope this will help.
