Image support in general

[im-n1]

There is a project called ranger which has image support.

from readme:

w3m for the w3mimgdisplay program to preview images

Hope it will help you to implement image views.

Let me consider it. Thank you for your suggestion

Here is an example:

I was kinda curious so I have advanced a bit. I'm in touch with lead Ranger developer and I asked him for help. This is what he replied:

Hi Pavel,

Image rendering in the terminal is a messy subject and is generally
unstable, but perhaps still worth trying ;)

ranger supports multiple methods for rendering images, w3mimgdisplay is
one of them.  Another promising option is the recently started project
"Ueberzug" (https://github.com/seebye/ueberzug)

Both programs are standalone executables that read their commands
through STDIN.  The format of the command differs between the programs. 
For ueberzug it's a simple JSON object as documented in ueberzug's
README.md file.  Should look like this:

echo '{"action": "add", "identifier": "xyz", "x": 0, "y": 0, "path":
"/some/path/some_image.jpg"}' | ueberzug layer

w3mimgdisplay's format is not well documented, last time I checked.  You
can get some inspiration on how to use it by checking
https://github.com/ranger/ranger/blob/master/ranger/ext/img_display.py ,
at the very end of the method "_generate_w3m_input".  It's some string
starting with "0;1;x-pos,y-pos,width,height,...". Perhaps you can find
the full specifications with some googling.

Good luck with your endeavor,
Roman

I guess we can try to give it a chance. Hm? ;)
