Edit: Discuss this in my previous (unclosed) discussion.
Images I share via Nextcloud cannot viewed in full resolution online. For example, view this image. It is not full resolution, as you can see after downloading it.
What is the best way to share full resolution images online via Nextcloud?
Nextcloud version (eg, 20.0.5) : 21.0.1
Operating system and version (eg, Ubuntu 20.04) : Ubuntu 20.04
Apache or nginx version (eg, Apache 2.4.25) : don't know, it's running on Cloudron
PHP version (eg, 7.4) : 7.4.3
My original question was asked incorrectly.
