Via Upload

Capture a photo via file upload as multipart/form-data then use the source parameter:

POST /v21.0/{group-id}/photos HTTP/1.1
Host: graph.facebook.com

source=%7Bimage-data%7D

/* PHP SDK v5.0.0 */
/* make the API call */
try {
  // Returns a `Facebook\FacebookResponse` object
  $response = $fb->post(
    '/{group-id}/photos',
    array (
      'source' => '{image-data}',
    ),
    '{access-token}'
  );
} catch(Facebook\Exceptions\FacebookResponseException $e) {
  echo 'Graph returned an error: ' . $e->getMessage();
  exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
  echo 'Facebook SDK returned an error: ' . $e->getMessage();
  exit;
}
$graphNode = $response->getGraphNode();
/* handle the result */

/* make the API call */
FB.api(
    "/{group-id}/photos",
    "POST",
    {
        "source": "{image-data}"
    },
    function (response) {
      if (response && !response.error) {
        /* handle the result */
      }
    }
);

Bundle params = new Bundle();
params.putString("source", "{image-data}");
/* make the API call */
new GraphRequest(
    AccessToken.getCurrentAccessToken(),
    "/{group-id}/photos",
    params,
    HttpMethod.POST,
    new GraphRequest.Callback() {
        public void onCompleted(GraphResponse response) {
            /* handle the result */
        }
    }
).executeAsync();

NSDictionary *params = @{
  @"source": @"{image-data}",
};
/* make the API call */
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                               initWithGraphPath:@"/{group-id}/photos"
                                      parameters:params
                                      HTTPMethod:@"POST"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                      id result,
                                      NSError *error) {
    // Handle the result
}];

Host: graph.facebook.com

url=%7Bimage-url%7D

/* PHP SDK v5.0.0 */
/* make the API call */
try {
