+#### Multiple images
+can be uploaded in a 2-step process. **First** you send each image to Twitter, like this:
+```php
+// these files to upload
+$media_files = array(
+    'bird1.jpg', 'bird2.jpg', 'bird3.jpg'
+);
+// will hold the uploaded IDs
+$media_ids = array();

+foreach ($media_files as $file) {
+    // upload all media files
+    $reply = $cb->media_upload(array(
+        'media' => $file
+    ));
+    // and collect their IDs
+    $media_ids[] = $reply->media_id_string;
+}
+```
+**Second,** you attach the collected media ids for all images to your call
+to ```statuses/update```, like this:
+
+```php
+// convert media ids to string list
+$media_ids = implode(',', $media_ids);
+
+// send tweet with these medias
+$reply = $cb->statuses_update(array(
+    'status' => 'These are some of my relatives.',
+    'media_ids' => $media_ids
+));
+print_r($reply);
+);
