I can not find anything about this subject so therefore this question.
I have inserted a picture in the text and wish to link it to a larger-sized edition. I know this was an option in Drupal 7
But with Drupal8 I can not.
I have installed IMCE.
Do I need a module or is this option just no longer present?
Now I think I found out!
The image must be highlighted and then the link button activated.
The IMCE popup window opens and the image to be linked to is selected.
