An image viewer and browser utility for the GNOME environment.
gThumb allows the filesystem to be browsed for images. They can be organized into catalogs, or viewed as a slideshow. Folders and catalogs can be bookmarked, and comments can be added to images.
This snap exists because the archive version does not have AVIF support.
To access removable media you have to connect the interface manually:
sudo snap connect gthumb-unofficial:removable-media :removable-media
