FIM (Fbi IMproved) is a highly customizable and scriptable image viewer
targeted at the users who are comfortable with software like the Vim.
FIM is multidevice: it has X support (via the SDL library),
it supports ASCII art output (via the aalib and libcaca libraries),
and because it derives from the Fbi image viewer (by Gerd Hoffmann),
it can display images in the Linux framebuffer console, too.
It offers many options for scaling, orienting, listing and rearranging
the ordering of images.
