markdown in kate with okular preview

SUMMARY

Markdown allow to embed images in document, it works very much like a link

[link text](https://image/link.png)
![embedded image](https://image/link.png)

STEPS TO REPRODUCE
1. Create a markdown with the above content.
2. load the file in Okular or Kate preview
3. embedded images should load from https, base64 or local file path

Comment 2 Laura David Hurka 2021-11-27 13:01:22 UTC 
Is this bug report about data URLs or about HTTP URLs now?
Comment 3 Paul Worrall 2021-11-28 18:24:05 UTC 
Local file system URLs (e.g. "/home/user/test.jpg") work OK in my tests, http and https don't, I haven't tried any other remote URLs.
