Again and again I had problems with posting pictures that I had taken with my smartphone camera. The same applies to bluesky.  
@dalto pointed out to me that I should enable html5 canvas for bluesky and the forum.

I use firefox with arkenfox user.js and the browser privacy settings are strict.

I then proceeded as follows:

- about:config

- privacy.resistFingerprinting

- privacy.resistFingerprinting.exemptedDomains: forum.endeavouros and bluesky added

- 

- Restart and everything works as desired.

If anyone has a better solution for me now, let me know 😉

That should work.

However, if you don’t want to completely disable resist fingerprinting, you can add an exception for only canvas data.

When a site wants your canvas data you should see an icon like this:

If you click that icon, you can allow access to your canvas data for that site.

I have already looked for this icon but did not find it when I called up the page. Therefore the solution via about:conf
