That's how it already works. The problem is URLs aren't cryptographic, so you can change the contents without breaking them. Though I vaguely recall there being an extension to HTML that fixes this.

Maybe hashing the full raw markdown including image urls would help?

SN release: OpenTimestamps timestamps

...and no:

```
{"parentHash":"e945eca22d6a5bddfcd30b7328ae80635a4ceaf0ff3a0cb7726197edcb0fabfd","text":"I wonder if you're hashing images... Let's try:\n\n![OpenTimestamps](https://opentimestamps.org/assets/images/logos@2x.png)","title":null,"url":null}
```

I guess it doesn't make much sense while you're not hosting images. But it would definitely be better if images were hosted on stacker news and hashed.
