Did you know that you don't need X-Windows for graphics on Linux? Here's a few console programs that can display graphics using the framebuffer:
Display and manage images directly from the command line.
A simple web browser without CSS and JS, can display inline images when switched to graphics mode with the -g param: 'links2 -g'
Play videos straight from the console! Can be a little tricky.
(And yes, I used a 5:4 monitor the screenshots.)
@lachs0r and "ranger" file manager can use w3mimgdisplay for image previews! but yeah, it's pretty much cursed so i gave up on it.
also it isn't documented well, but there's a good article about it, so anyone can use it in their shell scripts: http://blog.z3bra.org/2014/01/images-in-terminal.html .
(although sixel is better, afair fbi supported it)
