when sharing a pic throught nextcloud, you get something like this: https://xxx/index.php/s/dJnmyscRgJiKeNX
the problem for me, is when you post on a forum, using BB codes, you are expected to give that kind of code: [img]https://zupimages.net/up/18/08/il3w.jpg[/img] witch usually works.
but doesnt because the .* extention is not present.
