Something akin to the dark theme available within this forum?

You can try the hacker vision extension, if you are using Chrome.
On some pages it inverts the colors of the photos, however.

Are you referring to dark mode? If so, Dark Reader is also another option you can try out, works for Chrome, Firefox, and Safari (https://darkreader.org/). Hope this helps! :)
