201: Forbidden URI type for linked image file

You linked an image with [j]-> which causes the Aneamal Translator to generate a preview from your image automatically. The arrow is supposed to be followed by the path of a local image file. In your case it is followed by a different type of URI though, for example an absolute URL, a data URI or an URI fragment.

Solution

Use a path which is relative to the Aneamal root directory or a path that is relative to the current file’s directory:

% this is relative to the Aneamal root:
[j]->/en/example.png

% this is a file in the same directory as the current file:
[j]->example.png

If you prefer to link an image from a remote source, you can replace [j] with [i] which also adds an image to the webpage and supports absolute URLs, but without generating a preview:

[i]->https://example.org/imitch/example.png
