Nextcloud images not displaying in Discourse

[Falco]

I think we need an extension for images.

You need to explicitly tell it is a image if it has no image extension:

markdown:

![image](upload://v3ysVDuCq4lG7rPu28etHkdM2Pw.jpeg)
becomes

BBCode:

![](upload://v3ysVDuCq4lG7rPu28etHkdM2Pw.jpeg)
becomes

Or cheat with some query string:

becomes
