feh (http://www.linuxbrit.co.uk/feh) is an image-viewing application
for Linux based on the still-evolving imlib2 library from
http://www.rasterman.com as part of the famed Enlightenment window
manager. feh provides both single-image viewing as well as the ability
to run a slide show.
feh can create image montages and image thumbnails to allow you to
quickly find the images you want. feh can also load images from a URL
over an HTTP link, which is handy for viewing remote images from
another Web site.
For scriptwriters, feh can output a list of images similar to the file
lists output by the ls command. feh, though, can also output image
sizes such as width and height. This can be very useful for image
Once you load images, you can zoom, pan, rotate, sharpen, smooth, and
manipulate the images. feh is an image viewer, not an editor though.
For image editing, you probably want to use an application such as the
feh isn't the only image viewer out there, and both the KDE and GNOME
desktops include built-in image-viewing applications. Other image
viewers include gThumb (http://gthumb.sourceforge.net), GNOME Photo
Collector (http://gpc.sourceforge.net), and ShowImg
(http://ric.jalix.org/progs/ShowImg). However, my favorite image viewer
remains the shareware xv from http://www.trilon.com/xv.
