How are image links generated?

Well, i’m mostly interested in getting the original link.

Right now if Copy link address:

on my picture above i get

https://global.discourse-cdn.com/meta/original/3X/a/3/a37df25f15fccd47dc543f3d5751d81cb61dbe6b.jpeg

which even although has original in the name, is not the same as

https://cdck-file-uploads-global.s3.dualstack.us-west-2.amazonaws.com/meta/original/3X/a/3/a37df25f15fccd47dc543f3d5751d81cb61dbe6b.jpeg.

My point is that if in the future discourse would change the cdn, all the links with the old cdn will be broken.
