It happens if the server configuration “allow_url_fopen” is off and the image comes from an URL.
As allow_url_fopen leads to security issues in some old versions of PHP it would be the best solution to not use URLs at all. But I think my interface don’t allow directory paths and inserts the URL directly so I’ll have to change it.
