Question

I try to post my image link to Facebook fan page using Facebook C# SDK.

var client = new FacebookClient(this._accessToken);
dynamic parameters = new ExpandoObject();
parameters.message = "Check out this funny article";
parameters.link = "http://photos-f.ak.fbcdn.net/hphotos-ak-snc6/260418_185563101499189_124421460946687_425466_2105002_t.jpg";
parameters.picture = "http://photos-f.ak.fbcdn.net/hphotos-ak-snc6/260418_185563101499189_124421460946687_425466_2105002_t.jpg";
parameters.name = "My Picture";
parameters.caption = "My Picture Caption";
parameters.description = "";
dynamic result = client.Post("{Fan page ID}/feed", parameters);

An error occur like below.

(OAuthException) (#100) FBCDN image is not allowed in stream:
http://photos-f.ak.fbcdn.net/hphotos-ak-snc6/260418_185563101499189_124421460946687_425466_2105002_t.jpg

But if i set “picture” parameter to empty string it work perfectly.

How could i fix this problem?

Facebook doesn’t allow you to re-post or hot-link images that are hosted on their CDN. They added this policy and error message back in June 2010. You will need to upload this photo to some kind of non-Facebook server or photo sharing site and then use that url.
