What I tried to do + what happened

Using G-Mail as an example (though I've also seen it happen in GitHub), say I open the email editor, dropping me into firenvim. I add some text. Then I take a screenshot, :wq inside firenvim, and paste the screenshot into the editor. Finally, I re-enter firenvim, and poof, the embedded screenshot is lost. This is incredibly annoying and, without careful foresight, can lead to a lot of lost work.

I have absolutely no idea whether this has a solution, but one thing that comes to mind is the magma-nvim plugin* for interacting with Jupyter notebooks in Neovim. Somehow, magically, this plugin allows data visualizations to be displayed inside Neovim, suggesting it should be possible to "show" images too.

* Disclaimer: It's unclear to me whether the images actually persist. But anyway, better than no starting point at all!
