Currently the image field rendering in QWeb using the /web/image controller is done in web_editor. However there is no link between the web editor and the rendering. The rendering can therefore be moved directly in web. During the move two options have been added to the rendering of image field : * qweb_img_raw_data: fallback on standard base64 behavior that is otherwise impossible to achieve; * qweb_img_responsive: True by default, add the img-responsive class that is not always requested; Thanks.
