I made a small Vim 9.2+ plugin called thumb.
Put the cursor on an image path → → popup the image.
Select LaTeX in Visual mode → → render it as an image popup.
For example: Put the cursor on and run: Or select: and run: It uses Vim's native popup image support, with Python/Pillow for image conversion and matplotlib for LaTeX rendering.
No mappings are installed, so you can add your own: GitHub: Requires Vim 9.2+, Python 3, Pillow, and matplotlib.
Feedback welcome, particularly around the popup positioning/rendering.
