+
+Advantages over @command{w3mimgdisplay}:
+@itemize
+@item Support for Wayland: Sway, Hyprland, niri and Wayfire
+@item No race conditions as a new window is created to display images
+@item Expose events will be processed, so images will be redrawn on switch
+workspaces
+@item Tmux support on X11, Sway and Hyprland
+@item Terminals without the @env{WINDOWID} environment variable are supported
+@item Chars are used as position - and size unit
+@item No memory leak (usage of smart pointers)
+@item A lot of image formats supported (through OpenCV and libvips).
+@item GIF and animated WEBP support on X11, Sixel, Sway and hyprland
+@item Fast image downscaling (through OpenCV and OpenCL)
+@item Cache resized images for faster viewing
