您需要制作一个顶版图像的画册,然后是用面对面的胶卷制作的。

// for making a facebook album u have to make a multi-part form request
//to this url https://graph.facebook.com/100002232753228/albums
//where 100002232753228 is the fbid of the user and with form fields access_token,name,message, for reference go to -http://developers.facebook.com/docs/reference/api/album/

//To upload a foto to album send multi-part data to the url - https://graph.facebook.com/102657189818706/photos

//where 102657189818706 is the facebook id of the album created
