This is a very silly question. I\'m a beginner with facebook Javascript SDK. So I\'m trying to make a the user\'s profile image to show I used this code

    /me/picture (or /{user id}/picture) returns an HTTP 301 redirect to the image location so you can embed it directly into an <img src...

    If you want to retrieve the URL and use it yourself you need to specifically request it as a field, via :

     /{user id}?fields=picture

    or

     /me/?fields=picture

    You can include other fields too, but I'm assuming you just want the photo right now.

    This is sure shot, Proved to be working with facebook graph api 2.5. This is the sample HTML Please see the changes I have made in FB.api() function.

     <!DOCTYPE html>
    <html>
    <head>
    <title>Facebook Login JavaScript Example</title>
    <meta charset="UTF-8">
    </head>
    <body>

    <!--
      Below we include the Login Button social plugin. This button uses
      the JavaScript SDK to present a graphical Login button that triggers
      the FB.login() function when clicked.
    -->
    <img src="" id="profileImage"/>

    <div id="status">
    </div>

    </body>
    <script>

        // This is called with the results from from FB.getLoginStatus().
        function statusChangeCallback(response) {
            console.log('statusChangeCallback');
            console.log(response);
            // The response object is returned with a status field that lets the
            // app know the current login status of the person.
            // Full docs on the response object can be found in the documentation
            // for FB.getLoginStatus().
            if (response.status === 'connected') {
                // Logged into your app and Facebook.
                testAPI();
            } else if (response.status === 'not_authorized') {
                // The person is logged into Facebook, but not your app.
                document.getElementById('status').innerHTML = 'Please log ' +
                        'into this app.';
            } else {
                // The person is not logged into Facebook, so we're not sure if
                // they are logged into this app or not.
                document.getElementById('status').innerHTML = 'Please log ' +
                        'into Facebook.';
            }
        }

        // This function is called when someone finishes with the Login
        // Button.  See the onlogin handler attached to it in the sample
        // code below.
        function checkLoginState() {
            FB.getLoginStatus(function(response) {
                statusChangeCallback(response);
            });
        }

        window.fbAsyncInit = function() {
            FB.init({
                appId      : 'XXXXXXXXXXXX',
                cookie     : true,  // enable cookies to allow the server to access
                                    // the session
                xfbml      : true,  // parse social plugins on this page
                version    : 'v2.5' // use graph api version 2.5
            });

            // Now that we've initialized the JavaScript SDK, we call
            //FB.getLoginStatus().  This function gets the state of the
            // person visiting this page and can return one of three states to
            // the callback you provide.  They can be:
            //
            // 1. Logged into your app ('connected')
            // 2. Logged into Facebook, but not your app ('not_authorized')
            // 3. Not logged into Facebook and can't tell if they are logged into
            //    your app or not.
            //
            // These three cases are handled in the callback function.

            FB.getLoginStatus(function(response) {
                statusChangeCallback(response);
            });

        };

        // Load the SDK asynchronously
        (function(d, s, id) {
            var js, fjs = d.getElementsByTagName(s)[0];
            if (d.getElementById(id)) return;
            js = d.createElement(s); js.id = id;
            js.src = "//connect.facebook.net/en_US/sdk.js";
            fjs.parentNode.insertBefore(js, fjs);
        }(document, 'script', 'facebook-jssdk'));

        // Here we run a very simple test of the Graph API after login is
        // successful.  See statusChangeCallback() for when this call is made.
        function testAPI() {
            console.log('Welcome!  Fetching your information.... ');
            FB.api('/me', function(response) {
                console.log('Successful login for: ' + response.name);
                console.log('Successful login for: ' + response.id);
                console.log('Successful login for: ' + response.email);
                var im = document.getElementById("profileImage").setAttribute("src", "http://graph.facebook.com/" + response.id + "/picture?type=normal");
                document.getElementById('username').innerHTML =response.name;
            });
        }

    </script>
    </html>

    You can get specific sizes of the profile pic as well: 

    FB.api("/me/picture?width=180&height=180",  function(response) {

        console.log(response.data.url);

});

    See the Facebook documentation to see what different picture sizes you can get.

    And a complete demo with login at: Get Facebook Profile Picture with Javascript SDK

    FB.api('/me/picture') will return a redirect to the image URL, so it'll be of no use for you:
    alt text
    The way you are using is valid as mentioned in the documentation (Reading section). Maybe this is related but I don't know if it's totally valid or not.
