 ### Image Service
-This functionality is still buggy. Check back again later. Sorry :(
+Before using images in messages you have to upload an image to GroupMe's image service.
+
+```php
+require 'vendor/autoload.php';
+$c = new GroupMeApi\Client('API-KEY');
+$res = $c->uploadImage('my_image_file.png', 'image/png', 'testpic');
+```
+
+If the upload was successfull, the return variable contains the image url in `$res['payload']['url']` or an error message in `$res['error'][]`.
