I am using `https://graph.facebook.com/" + FB_id + "/feed` as the target for a post to publish to the feed of a user as described here: <http://developers.facebook.com/docs/reference/api/> (search for "Publishing" section).

The picture parameter is described here:
<http://developers.facebook.com/docs/reference/api/post/>

But I was unable to find what is the recommended image size to be used when publishing like this.

I know the Image is displayed on both the user's own time-line and an hid friends' feeds and it would seem like they are differently sized in those two places.

So, What are the recommended picture dimensions when posting to Facebook Feed via the API Grpah ?
