I looked for a feature request for image formatting, but couldn’t find one. I know there have been discussions on Discord about it.
It would be nice if Obsidian operated more like Typora, where you can reference relative paths to files like this:
or
<img src="..\path\to\image.png" alt="My Image" style="zoom:50%;" />
There is a feature request for this: https://forum.obsidian.md/t/relative-paths-to-unrecognized-file-types-in-the-vault/4251
