How To Fix Image Preview Issues in Ranger with w3m on Ubuntu 18.04

Ubuntu 9

Ranger is a powerful file manager for the terminal. It provides a minimalist, yet visually appealing interface for managing files and directories. One of its standout features is the ability to preview files, including images. However, sometimes users may encounter issues with image previews, especially on Ubuntu 18.04. This article will guide you on how to fix image preview issues in Ranger with w3m on Ubuntu 18.04.

Quick Answer

To fix image preview issues in Ranger with w3m on Ubuntu 18.04, you need to install the necessary dependencies (w3m, w3m-img, and rxvt-unicode-256color), configure Ranger to enable image previews, and restart Ranger. If the issue persists, you can try using an alternative terminal emulator like Kitty.

Prerequisites

Before we start, make sure you have sudo or root privileges to install necessary packages.

Installing Required Dependencies

To enable image preview in Ranger, we need to install a few dependencies. The first one is w3m, a text-based web browser. It is required because Ranger uses it to render images in the terminal. The second one is w3m-img, a package that enables w3m to display images. Lastly, we’ll install rxvt-unicode-256color, a color-enabled rxvt-unicode terminal emulator.

Open your terminal and run the following commands:

sudo apt install w3m
sudo apt install w3m-img
sudo apt install rxvt-unicode-256color

The sudo command is used to execute the following command with root privileges. The apt install command is used to install new packages on Ubuntu.

Configuring Ranger

After installing the necessary dependencies, the next step is to configure Ranger to enable image previews.

Open the Ranger configuration file with your preferred text editor. Here we’re using vim:

vim ~/.config/ranger/rc.conf

In this command, ~/.config/ranger/rc.conf is the path to the Ranger configuration file.

Find the line that says set preview_images false and change it to set preview_images true. This will enable image previews in Ranger.

Next, find the line that says set preview_images_method none and change it to set preview_images_method urxvt. This tells Ranger to use urxvt as the method for displaying image previews.

After making these changes, save the file and exit the text editor.

Restarting Ranger

For the changes to take effect, you need to restart Ranger. Simply close the current Ranger session and start a new one. Now, when you navigate to a directory containing images in Ranger, you should see image previews displayed in the terminal.

Troubleshooting

If image previews are still not working after following the above steps, you might want to try using an alternative terminal emulator. One such emulator is Kitty. To install Kitty, run the following command:

sudo apt install kitty

Then, change the preview_images_method in the Ranger configuration file to kitty:

set preview_images_method kitty

After making this change, restart Ranger.
