Ueberzug is a command line utility which draws images on terminals using child windows.

It has several advantages over w3mimgdisplay:

- no race conditions, as a new window is created to display images - expose events will be processed, so images will be redrawn on switched workspaces - tmux support (excluding multi pane windows) - terminals without the WINDOWID environment variable are supported - chars are used as both the position and size unit - no memory leak (and unlimited cache)
