gThumb is an image viewer, editor, browser and organizer. It is designed to be well integrated with the GNOME 3 desktop.
As an image viewer gThumb allows to view common image file formats such as BMP, JPEG, GIF (including the animations), PNG, TIFF, TGA and RAW images. It is also possible to view various metadata types embedded inside an image such as EXIF, IPTC and XMP.
As an image editor gThumb allows to scale, rotate and crop the images; change the saturation, lightness, contrast as well as other color transformations.
As an image browser gThumb shows the thumbnails of the images saved on your disk, allows to perform the common operations of a file manager such as copy, move and delete files and folders. Furthermore there is a series of image specific tools such as JPEG lossless transformations; image resize; format conversion; slideshow; setting an image as desktop background and several others.
As an image organizer gThumb allows to add comments and other metadata to images; organize images in catalogs and catalogs in libraries; search for images and save the result as a catalog.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for Red Hat Enterprise Linux (RHEL) 8 and RHEL 7, from the 7.6 release onward.
The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective Extra Packages for Enterprise Linux (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below.
The EPEL repository can be added to RHEL 9 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 8 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 7 with the following command:
sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Adding the optional and extras repositories is also recommended:
sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms"
sudo yum update
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again or restart your system to ensure snap’s paths are updated correctly.
To install gThumb Image Viewer, simply use the following command:
sudo snap install gthumb --edge
Browse and find snaps from the convenience of your desktop using the snap store snap.
