Iphone Posting on wall with FBConnect

I am using the latest facebook sdk.
Everything works fine even the post on wall feature.
Thing is that the post to wall dialog contains minimal information. Just a textbox and a small label reading "... via app-name".
I have used the sample code snippet which provides things like 'caption' and 'description' but these are NOT shown in the post to wall dialog.
I have seen other apps with captions, descriptions and even a large image attached to the post.
How can I show these objects (caption, description, image etc..) using the facebook sdk ?
Thanks
I don't use the Facebook SDK so I just send POST requests with the necessary values. Similar to this:

There's another tutorial on the same blog that does use the SDK:
