If I create an image/jpeg tiddler and point to an external image using the _canonical_uri field, say https://upload.wikimedia.org/wikipedia/commons/9/91/Foro_Romano_Forum_Romanum_Roman_Forum_(8043630550).jpg
The image is displayed in the tiddler.
But if I try and display that image tiddler in another tiddler via the image link syntax it fails. What am I doing wrong?
[img[external_image_tiddler]]
Thanks
