Image previews

Open an image file and nxvim renders the picture inline instead of its raw bytes — image.nvim’s behavior, built in, with no terminal-specific plugin to wire up. Each client draws it the native way: ratatui-image in the terminal (Kitty/Sixel/iTerm2 graphics, with a block-cell fallback), a textured quad in the GPU GUI, and an out-of-band <img> in the browser build.

The feature is opt-in through one option.

Enabling it

'imagepreview' (nxvim-native, off by default) turns it on:

nx.o.imagepreview = true        -- or :set imagepreview

With it on, opening a file with an image extension — png, jpg/jpeg, gif, bmp, webp, tiff/tif, ico, tga (case-insensitive) — loads it as an inert preview buffer: the bytes are never decoded as text, the rope stays empty, and the window projects an image the client paints. The path is retained, so the buffer still has a name. With the option off, an image file opens as ordinary binary text, exactly as before.

There are no special commands or keymaps — opening is the usual :e <path> or a file argument on the command line.
