About:
Lsix is a command-line utility that leverages the Sixel graphics protocol to display image thumbnails directly within a terminal emulator. It functions similarly to the 'ls' command but renders previews for supported image files instead of text filenames. This allows users to visually inspect directories of images without leaving the command line or launching a separate GUI application.

Key Features:

Native terminal rendering using Sixel graphics
Works with standard command-line wildcards and piping
Supports common image formats (JPEG, PNG, GIF, WebP)
Displays image metadata (dimensions) alongside thumbnails

Use Cases:

Quickly browsing and verifying contents of image directories via CLI
Previewing images in remote SSH sessions where X11 forwarding is unavailable
Scripting visual checks for image processing pipelines

Alternatives:

chafa – Chafa converts images to ANSI/Unicode character art or Sixel, offering more stylistic options but Lsix focuses strictly on high-fidelity Sixel thumbnails.
lsix – Lsix is specifically optimized for Sixel terminals, whereas tools like 'viu' or 'imgcat' may rely on other protocols or terminal-specific features.
