If you create an exercise, you may want to add your own static content such as images in the exercise description (descr.html or descr.md).
Learn-OCaml provides this feature, so that you can either add images hosted in an external domain, or images statically served by the Learn-OCaml server itself (which can be handy for summative exams, for example, when remote resources are blocked).
In order to include OCaml.png in an exercise called demo, you just need to:
<repo>/exercices/demo/subdirectory. (The name of the subdirectory is free.)OCaml.png in there.<repo>/exercises/demo/descr.html (resp. <repo>/exercises/demo/descr.md), use the following syntax:<img src="/static/demo/subdirectory/OCaml.png" alt="fallback text"> (resp. ).Note that we can’t use relative URLs, hence the leading /.
If you want to fix the width (or height) of an image in descr.html or descr.md, you can use the usual HTML syntax:
<img src="/static/demo/subdirectory/OCaml.png" alt="fallback text" width="400px">
