Got it. The magic is not to call the external method by container.createThumbnail() but use absolute URL to the external method. In the page template I have to use: <img tal:attributes="src string:${container/absolute_url}/createThumbnail?imagepath=${imgpath}"/> Thanks for pointing me in the right direction.
