# >humb; Manual V&manual-version;

## Introduction

>humb; is an image viewer and browser written for the GNOME environment. It lets you browse your hard disk, showing you thumbnails of image files and view single images of many different formats.

The most common image formats are JPEG and GIF. The JPEG format is good for medium and big sized images because it has a high compression rate keeping a good image quality. The GIF format is used in Web pages for displaying little animations or little static images. Another important image format is PNG, this format is very common on Unix platforms and is considered a replacement of the GIF format which has license issues.

>humb; supports all this formats and many others, it also displays GIF animations.

>humb; not only lets you view image files but has many other features such as add comments to images, organize images in catalogs, print images, view slideshows, set your desktop background, and more.
