What is the best way to share full resolution images online?

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.

it’s fair trying to asdk the same question again but as i tried to explain… as there is a github-issue filed there’s nothing more we could do on the forum than just discussing it on and on… that’s why a GH-issue “solves” your thread by definition.
any further discussion about it should take place on github.

but it’s not forbidden to go on discussing it here… “solved” doesn’t mean “closed”

closed is this thread now. since it’s a crossposting.

you could try and “bump” your initial thread from time to time with a new comment.
