sxiv: Simple (or small or suckless) X Image Viewer
sxiv is an alternative to feh and qiv. Its only dependency besides xlib is
imlib2. The primary goal for writing sxiv is to create an image viewer, which
only has the most basic features required for fast image viewing (the ones I
want). It has vi key bindings and works nicely with tiling window managers.
Its code base should be kept small and clean to make it easy for you to dig
into it and customize it for your needs.

Features
--------
@ -15,14 +15,9 @@ Features
* Thumbnail mode: grid of selectable previews of all images
* Ability to cache thumbnails for fast re-loading
* Basic support for multi-frame images
* Load all frames from GIF files and play GIF animations
* Display image information in window title
Additional features, that need to be enabled at compile-time (in *config.h*),
because they depend on additional libraries:
* Load all frames from GIF files and play GIF animations (requires giflib)
* Auto-orientate JPEG images according to their EXIF tags (requires libexif)
Screenshots
