This image viewer is integrated with GTK+, which is similar to GNOME, and supports multiple image formats, meaning you can view a single image or a collection of images in a single window.

#Image viewer linux install

However, if it is not installed on your previous CentOS versions, you can easily install it from the main software repository. With this method you won't be able to manage your installation from the package manager, though.Eye of Gnome is the default image viewer on RHEL 8 based systems like RockyLinux 8, CentOS 8, and AlmaLinux 8, so it is most likely already installed on your system. Instead of using checkinstall to generate a debian package and install it via the package manager you can just as well run make install. If you are confident with adding a third-party PPA you can install Viewnior by using the following commands: sudo add-apt-repository ppa:desdelinux/viewniorĪlternatively you can compile Viewnior from source: git clone Before proceeding with the installation please make sure to read the following Q&As on PPAs and their potential dangers:Īre PPA's safe to add to my system and what are some 'red flags' to watch out for? You can install it from the Software Centre or by running the following command: sudo apt-get install viewniorĪ third-party PPA for Viewnior is now available. One more reason to choose Viewnior is that isn't affected by this image scaling bug that's prevalent in many other GTK-based image viewers (see here for other solutions to this bug).Īs of Ubuntu 14.10 Viewnior is now part of the official Ubuntu repositories. Viewnior has been the fastest image viewer for me by far: You can do a lot more with feh and there are many more options to experiment with, so for more information, please see man feh and the Ubuntu manpages online. Hence your custom 'open-with' command/launcher should use this -scale-down option, for the times you want to view individual pictures.Ģ) In the case of creating an index print and saving to file you could use the following command: feh -I -preload -o index.pngģ) You can also use the thumbnail option ( -t), which is like the previous command, but allows you to click the thumbnails from the created file: feh -t -preload -scale-down -o thumbprint.png Note: when not running in fullscreen mode ( -F), you may need to supply the -scale-down command switch so the pictures fill your desktop, but not display at their actual size (which could be 4000x3000 and would not fit the screen). You could also add this command, with slight modification, as a 'custom' action, context menu item in a file manager such as Thunar ( feh -F -D 3 -cycle-once %F): see my answer here regarding Thunar custom actions. Even with high resolution pictures (5-6 mb each), you can flick through the pictures incredibly quickly. You can use your mouse scrollwheel to flick back and forth through the pictures while the slideshow is running. Configurable keyboard shortcuts are used to control it.įeh operates in various modes such as slideshow, montage, index, and thumbnail, although you can of course view pictures individually, and also save the results of the index or thumbnail viewing to file.Īll the following examples assume you use terminal to cd to the folder containing the pictures first:ġ) To start a fullscreen slideshow, and for it to display all the loadable pictures in the folder with a 3 second gap and then exit, you could run: feh -F -D 3 -cycle-once * It supports filelists, various image sorting modes, image captions and more. It is especially aimed at commandline users who need a fast image viewer without huge GUI dependencies, though it can also be started by (graphical) file managers to view an image. However, you can add various feh commands as custom actions to filemanagers such as Nautilus and Thunar so that you can activate feh via the context menu when browsing your files.įeh is a mode-based image viewer. For sheer speed, feh is the most responsive image viewer you'll ever come across it might take a bit of getting used to as it is managed from the command line.
