 @return [JSON object] HTTP response JSON object. Returns ImageSizes objects array if generate_objects flag is set

 @example
          rest_client.update_image_sizes(image_sizes_obj)
          rest_client.update_image_sizes(image_sizes_obj,true)
          rest_client.update_image_sizes(image_sizes_obj_array)
          rest_client.update_image_sizes(image_sizes_obj_array,true)
