why dont we have a recogniseable image as an example of the trope (eg Discworld) instead of the blurry orange thing?

Unspoilered most of the Dark City and Crimson Permanent Assurance examples. Please don't spoiler an entire example or just the title, it makes it impossible for anyone to know whether they should read it or not.

Remember, Our Handling Spoilers page says:

"Spoiler tagging the name of the work is worse than useless. If you do that, there's a special hell waiting for you."
