Question: I am using iframe to display pdf(asp.net mvc3).While PDF is in the iframe menu item is not visible ,means it is hiding behind the iframe.
Can anyone let me know how to aolve this.

Thanks in advance.

Answer: 
You must request the API with the [field\_expansion syntax](https://developers.facebook.com/docs/reference/api/field_expansion/) 

These api requests works :

`$results = $facebook->api('/me', array('fields' => 'picture.height(300).width(300)'));`

`$results = $facebook->api('/me', array('fields' => 'picture.type(large)'));`
I found a workaround - profile pictures of various sizes can still be accessed via an FQL query:

```
$pic = $facebook->api(array('method'=>'fql.query', 'query'=>"SELECT pic_big FROM user WHERE uid=$fb_uid"));

```

("pic\_big" is equivalent to "type=large" - see [here](https://developers.facebook.com/docs/reference/fql/user/)).

This still doesn't explain why the GRAPH call suddenly broke though, or why image sizes don't seem to be accessible via Graph at all anymore (which I'd still like to know)...but at least there's *some* way to get the other size photos.

Gotta love Facebook and their top-notch reliability...
