Facebook PHP SDK: Getting (cropped) album cover

问题

I am using Facebook's PHP SDK and Graph API to obtain all albums from one user, and then display them to him so he can select which album he will browse. I want them displayed in a grid, just like Facebook does: every picture with the same width and height.

The problem is that when I do:

   $fb->api('/' . $album_id . '/picture?access_token=' . $accessToken 

I get a version of the picture with the original dimensions, and not the way that Facebook shows them to you when you click on Photos, i.e. a cropped version adjusted to a fixed size.

I have tried adding ?square to the request, but still getting the same result.

Any ideas?

Supported types for albums are thumbnail, small and album and to retrieve one of them you use:

$fb->api('/' . $album_id . '/picture?type=album&access_token=' . $accessToken
