About gThumb

gThumb 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.

gThumb supports the most common graphics formats, including JPEG, GIF, TIF, and PNG. gThumb will also display other less common image types if the supporting libraries are installed, including TGA, ICO, BMP, XPM, and others.

Some support for RAW image types is included, especially if the dcraw program is installed on your system.

gThumb not only lets you view image files but has many other features such as adding comments to images, organizing images into catalogs, printing images, slideshows, setting your desktop background, and more.

gThumb includes a tool to import photos from attached cameras and memory card readers.

gThumb can read EXIF, XMP, and IPTC metadata that is commonly embedded in files.

gThumb provides a systems of extensions (or plug-ins), to allow users to extend the functionality of gThumb.
